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– when the signal is withdrawn, nset is set to 0 for all drives, and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