SIMODRIVE 611A Installation and Start–Up Guide/IAA/–04.97 Edition
> 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])
S terminal 112: Setting–up operation (V
min
3–ph. 24V AC or 34 V DC)
– the V
DC
link
– closed–loop control is inhibited
– regenerative feedback is not possible, i.e. when braking, V
DC
link
can be >600V!
– this function is interrogated with the start inhibit signal, terminal AS1–AS2.
!
Caution
For induction motors, even for low V
DC
link,
high speeds can be reached!
S terminals AS1–AS2: start inhibit signal
– terminals AS1–AS2 closed means ”start inhibit is effective” (setting–up operation)
S terminals 111, 113, 213: signal contact, internal line contactor
– terminals 111 – 113: NO contact
– terminals 111 – 213: NC contact (for I/R 16kW and UE 10kW only from
Order No. 6SN114V–1VV01–0VVV )
S 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)
S terminal 9: FR+:
– 24V enable voltage
– max. load capability of the power supply:500mA (corresponds to 8 slots;1 optocoupler input
requires 12mA)
S 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)
S 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: I
N
4 A, type gL
S Fan 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: I
N
1.5 A (motor protection circuit–breaker)
