SIMODRIVE 611 Planning Guide (PJU) – 05.01 Edition
S For 611D/611U/ANA/HLA drives, the pulses are cancelled after a selectable
speed has been fallen below or after a selectable timer has expired. The
drives are braked along the set limit (MD 1230, 1235, 1238).
For spindles, a ramp can only be achieved using regenerative limiting
(MD 1237).
Line supply connection 2–ph. 360 ... 457 V AC / 45 ... 53 Hz; 400 ... 510 V / 57
... 65 Hz.
Coil voltage of the internal line connector is connected directly to the line supply
(do not connect between the I/R module and reactor).
The terminals are only provided at the 80/104 kW and 120/156 kW I/R modules.
Fuse: I
N
≥ 4 A, version gL
Note
If, for the 80/104 kW or 120/156 kW I/R module, the line supply voltage fails at
terminals L1, L2, or fuses F1, F2 blow, then only the pulses in the I/R module
are inhibited and the internal line contactor drops out.
This is displayed via the line supply fault LED and the ready relay as well as
the contactor signal contacts. In this case, after the internal line contactor has
been re–closed, terminal 48 must be inhibited, and after ≥ 1 sec, re–enabled or
the unit powered down/powered up.
Reset
The fault signal is reset using a button (pulse edge) between terminal R and 15.
For the SIMODRIVE 611 universal control module, the reset is effective, if in
addition, terminal 65 ”controller enable” is inhibited
For 611A MSD and AMM modules, the reset is effective if additionally terminal
63, 64, 65 or 48 are inhibited.
Setting–up operation
Terminal 112 is jumpered, as standard with terminal 9.
For a special application,
“setting–up operation with reduced DC link voltage”,
the DC link controller is inhibited when terminal 112 is opened. The power in-
feed is supplied through a three–phase isolating transformer with a reduced
secondary voltage. This function is only available for 611 analog with user–
friendly interface for 1FT5 feed motors. Regenerative feedback is no longer
possible, i.e. when braking, V

> 600 V DC.
Notice
For induction motors or for vertical 1FT5 feed axes, high speeds can even be
achieved at lower V
