Figure 8-45 OFF1 brake function
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, e.g. DI3 is active.
OFF1 is low active.
When simultaneously selecting the various OFF commands, 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 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.
