Note
• 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).
• BICO parameter P0840 is pre-assigned by defining the command source using P0700.
• The ON and the following OFF1 command must have the same source.
• If the ON/OFF1 command is set for more than one digital input, then only the digital input,
that was last set, is valid.
• OFF1 is active low.
• When various OFF commands are selected simultaneously, the following priority applies:
OFF2 (highest priority) – OFF3 – OFF1.
• OFF1 can be combined with DC current braking or compound braking.
• When the motor holding brake MHB (P1215) is activated, for an OFF1, P2167 and P2168
are not taken into account.
OFF2
The converter pulses are immediately cancelled by the OFF2 command. Thus the motor
coasts down and it is not possible to stop in a controlled way.
Note
• 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).
• 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 digital input 2 → P0702 = 3).
• OFF2 is active low.
• When various OFF commands are selected simultaneously, the following priority applies:
OFF2 (highest priority) – OFF3 – OFF1.
