NOTE
¾
OFF1 can be entered using a wide range of command sources via BICO
parameter P0840 (BI: ON/OFF1) and P0842 (BI: ON/OFF1 with reversing).
¾ BICO parameter P0840 is pre-assigned by defining the command source using
P0700.
¾ The ON and the following OFF1 command must have the same source.
¾ If the ON/OFF1 command is set for more than one digital input, then only the
digital input that was last set, is valid, e.g. DIN3 is active.
¾ OFF1 is low active
¾ When simultaneously selecting the various OFF commands, the following
priority applies: OFF2 (highest priority) – OFF3 – OFF1
¾ OFF1 can be combined with DC current braking or compound braking.
¾ When the motor holding brake MHB (P1215) is activated, for an OFF1, P2167
and P2168 are not taken into account.
OFF2
The inverter pulses are immediately cancelled by the OFF2 command. This means
that the motor coasts-down and it is not possible to brake in a controlled fashion.

NOTE
¾
The OFF2 command can have one or several sources. The command sources
are defined using BICO parameters P0844 (BI: 1. OFF2) and P0845 (BI: 2.
OFF2).
¾ As a result of the pre-assignment (default setting), the OFF2 command is set to
the BOP. This source is still available even if another command source is
defined (e.g. terminal as command source
→ P0700 = 2 and OFF2 is selected
using DIN2 → P0702 = 3).
¾ OFF2 is low-active
¾ When simultaneously selecting the various OFF commands, the following
priority applies: OFF2 (highest priority) – OFF3 – OFF1
