Jog mode (JOG)
When the digital input configured as JOG is activated, the motor
can be operated in jog mode. This mode is used, for example, for
manual setting up of a machine by issuing a start signal on the FW
or REV input with a relatively low frequency without applying an
acceleration ramp to the motor.
X Input under PNU A038 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. Set a frequency below about 5 Hz.
X Because the start signal in jog mode is issued through the FWD-
or REV input, PNU A002 must be set to 01.
X Under PNU A039, you determine how the motor is to be
braked.
X Program one of the digital inputs 1 to 8 as JOG by entering the
value 06 under the corresponding PNU (C001 to C008).
By default, JOG is assigned to digital input 3.
