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– when the signal is withdrawn, nset is set to 0 for all drives, and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