Pulse enable
Controller enable: To power–up the drives, in addition
to terminal 65, terminals 663 and 81 must also be
energized. If terminal 65 is opened, the motor brakes
with the selected deceleration time (ramp–down time).
The pulses are canceled when n
min
is fallen below.
Ramp–function generator fast stop: The motor brakes
along the torque limit after terminal 81 has been ope-
ned. When n
min
is fallen below, either the pulses are
canceled, or the motor remains magnetized.

1) I=input; O=output; NC=NC contact; NO=NO contact (for signal: Closed=high, open=low)
2) The BERO can either be connected to X433 or to X432.
3) X433 is only available for Order No.: 6SN1121–0BA11–0AA1.
4) BERO type: 3–conductor PNP NO contact, e.g. BERO M30 Order No.: 3RG4014–0AG01 or
BERO M12 Order No.: 3RG4012–3AG01
The BERO cable must be shielded.
5) The cable shields of setpoint cables must be connected at both ends.
6) The terminal may only be used to enable the associated drive group.
