Caution:
If direct selection of torque control is used (P1300=22, 23) the OFF1 command is recognized as OFF2.
However, the OFF1 command is not recognized when torque control is selected indirectly (P1300=20, 21
and P1501=1). If indirect selection of torque control is used, it is recommended to program an OFF2
command using, for example a digital input or create the following circuit using the Free Function Blocks
(FFB):
Source
Torque switch-over
Source
ON/OFF1

Speed control with encoder feedback see P1460
Speed control without encoder feedback see P1470
