8.12 Jog Operation
Jog runs the motor at reduced speed, to allow alignment of the load or to assist
servicing. The motor can be jogged in either forward or reverse direction.
Jog is only available when the starter is controlled via the digital inputs (parameter
1A
Command Source = 'Digital Input'). To operate in jog, a programmable input
must be set to jog (refer to parameter 7A for details) and the input must be closed
when the start signal is applied.
CAUTION
Slow speed running is not intended for continuous operation due to reduced
motor cooling.
Jog operation causes the motor to heat faster than the rate calculated by
the motor thermal model. If you are using jog, install a motor thermistor or
allow sufficient restart delay (parameter 5P).
