Jog mode (JOG)
When the digital input configured as JOG is activated, the motor
can be operated in jog mode. This mode is used, e.g. for manual
setting actions on machinery by issuing a start command on the
FWD or REV input with a relatively low frequency without applying
an acceleration ramp to the motor.
X Input under PNU A38 the frequency which is to be applied to
the motor when jog mode is active.
Make sure that the frequency is not too high, as it is applied
directly to the motor without an acceleration ramp. This could
cause a fault message to occur. Set a frequency below about 5 Hz.
X As the start command in jog mode is to be set via the FWD or
REV input, set under PNU A02 the value 01.
X Under PNU A39, you determine how the motor is to be braked.
X Program one of the digital inputs 1 to 5 as JOG, set the value
06 under the respective PNU (C01 to C05).

rotation) and 3 as JOG (jog mode).

Jog mode cannot be applied if the value set for the jog
mode frequency under PNU A38 is less than the start
frequency set under PNU b82 (a Section ”RUN operati-
onal”, Page 70)

Jog mode can only be activated when the frequency
inverter is in the Stop state.
