Simodrive F-16 Alarm Code Troubleshooting

We recently had a customer install a replacement 6SN1121-0BA11-0AA1 card into a 6SN1123-1AA00-0EA1 power module. When they installed the card it came up with an F-16 alarm code on the display of it, which references an “Illegal Power Module.” Using the instructions in the manual for the start-up of a replacement Simodrive card or power module we were able to get the customer back up and running with the steps below.

Simodrive Terminal and Relay Functions

Simodrive terminals and relay functions

X111: READY RELAY:

– terminals 72 – 73.1: NO contact in the quiescent state

– terminals 73.2 – 74: NC contact in the quiescent state

 

For S1.2=OFF, the relay switches if the following conditions are fulfilled:

– internal main contactor CLOSED (terminals NS1–NS2 connected, terminal 48 enabled)

– terminals 63, 64 =ENERGIZED

– no fault present (also not on feed drive 611A Standard, or 611D drives)

– feed drive with Standard interface or resolver is enabled for the ”ready” setting (terminals

663, 65)

 

For S1.2=ON, the relay switches if the following conditions are fulfilled:

– internal main contactor CLOSED (terminal NS1–NS2 connected, terminal 48 enabled)

– no fault present (also not on feed drive 611A Standard, and 611D drives)

– feed drive with Standard interface or resolver enabled for this ”ready” setting (terminals 663, 65).

 

X121: I2t_alarm and motor overtemperature:

terminal 5.1 – 5.2: NO contact in the quiescent state

terminal 5.1 – 5.3: NC contact in the quiescent state

This relay switches, if:

– the > heatsink temperature monitoring responds at the I/R

– the > motor temperature monitoring responds at the 611D feed drive

> heatsink temperature monitoring responds

– at the feed drive 611A user–friendly

> motor temperature monitoring responds

> heatsink temperature monitoring responds

> I2t–temperature monitoring responds (non–latching)

– at 611A Standard

> Motor temperature monitoring responds

> heatsink temperature monitoring responds

 

X171: Terminal NS1–NS2 (coil circuit of the internal line supply– and pre–charging contactor):

– is used to electrically isolate from the line supply (signal contact, terminals 111–213 must be interrogated)

– may only be switched if terminal 48 is open–circuit

 

terminal 48: Start

– has the highest priority

– Sequence: Pre–charging ON interrogation VDClinkw310V and VDClinkw√2*Vsupply–50V

> 500ms pre–charging contactor OUT, interrogation whether OUT, main contactor IN

>1s internal enable signals (for I/R and module group)

– saved during pre–charging

 

terminal 63: Pulse enable

– has the highest priority for pulse enable of all the modules

– acts instantaneously (without delay)

 

Terminal 64: Drive enable

– acts instantaneously on all modules

– when the signal is withdrawn, nset is set to 0 for all drives, and

> for main spindle drive / induction motor module 611 A, the pulses are canceled

after a speed, which can be set, is fallen below. The drive is braked along the ramp.

> for feed drives 611 A, after the selected timer stages have expired (as supplied: 240ms) all of the controllers and pulses are inhibited. The drive brakes along the current limit.

> for 611D drives, the pulses are deleted after a selectable speed has been fallen below and/or a time which can be set, has expired. The drive brakes along the set limits. (For spindles, a ramp can be achieved via regenerative limiting [kW])

 

terminal 112: Setting–up operation (Vmin3–ph. 24V AC or 34 V DC)

– the VDClink

– closed–loop control is inhibited

– regenerative feedback is not possible, i.e. when braking, VDClink can be >600V!

– this function is interrogated with the start inhibit signal, terminal AS1–AS2.

 

terminals AS1–AS2: start inhibit signal

– terminals AS1–AS2 closed means ”start inhibit is effective” (setting–up operation) terminals 111, 113, 213: signal contact, internal line contactor

– terminals 111 – 113: NO contact

– terminals 111 – 213: NC contact

 

terminal 19: FR–:

– reference ground, enable voltage

– floating (connected to the general reference ground, terminal 15 via 10kΩ)

– it is not permissible to connect terminal 19 with terminal 15 (connect to PE rail or X131)

 

terminal 9: FR+:

– 24V enable voltage

– max. load capability of the power supply:500mA (corresponds to 8 slots;1 optocoupler input

requires 12mA)

 

X 141: electronic voltages:

– terminal 7: P24 +20.4 to 28.8V / 50mA

– terminal 45: P15 +15V / 10mA

– terminal 44: N15 –15V / 10mA

– terminal 10: N24 –20.4 to 28.8V / 50mA

– terminal 15: M 0V

– it is not permissible to connect terminal 15 to PE (ground loop)

– it is not permissible to connect terminal 15 with terminal 19 (short–circuit via reactor, which internally connects terminal 15 with X131)

 

terminal L1–L2 for 80kW and 120kW – I/R

– is used to supply the coil of the internal line contactor

– is supplied directly at the line supply with 2–ph. 400V AC (not between I/R and reactor)

– fuse: INw4 A, type gLFan connection for 80 and 120kW I/R

– 3–ph. 360 to 510V AC , 45–65 Hz directly at the line supply (not between the I/R and reactor)

– observe the rotating field (phase sequence)!

– fuse: INw1.5 A (motor protection circuit–breaker)

– conductor connection with additional connection of the power supply at the DC link

– for this operating mode, terminals 2U1, 2V1 and 2W1 of the power supply must be supplied with the line supply voltage between the series reactor and I/R, otherwise the power supply will be destroyed! This is also valid for the monitoring modules!

Checking the Simodrive Power Section

Ohm Checking the Simodrive Power Section
Caution!  It must be assured that power is removed and the DC Bus has drained to a safe level before any connections are removed or checked!

Check out our website for all Siemens and Simodrive products.

After you are sure that the DC Bus has safely discharged , a DVM on the Diode scale can be used to detect if a  short circuit or open exists in the power section.  Readings will vary with module size.

Note:   P600 and M600 are the 600 V DC Bus connections.  U2, V2 and W2 are the motor connections.

• Disconnect the P600, M600 bus bars, U2, V2 and W2 connections.  This isolates the power module from the motor and DC Bus.
• Diode check between P600 and U2, then V2 then W2. There should be continuity with the – lead on P600 and the + lead on U2, V2 or W2.  Readings should be open with the leads reversed.
• Diode check between M600 and U2, V2, W2.  There should be continuity with the + lead on M600 and the – lead on U2, V2 or W2.  Readings should be open with the leads reversed.
• Diode check between P600 and M600.  There should be continuity with the + lead on the M600 and the – lead on P600.  The reading should be open with the leads reversed.
• Diode check between U2, V2 and W2.  All combinations should read open.

Note:  If all readings are open the internal DC Bus fuse is open.  If there is a 0Ω reading, there is a  short in the power circuit.
Note 2: Because of the capacitance in the power circuit, resistance checks will indicate a charging effect.  It is necessary to wait until the measurement has stabilized to determine if it is correct.  If possible, it is best to use a DVM with a diode check.
