L2002 Inverter

Jogging Command

The Jog input [JG] is used to command the motor to rotate slowly in small increments for manual operation. The speed is limited to

10 Hz. The frequency for the jogging operation is set by parameter A038. Jogging does not use an acceleration ramp, so we recommend setting the jogging frequency A038 to 5 Hz or less to prevent tripping.

When the terminal [JG] is turned ON and the Run command is issued, the inverter outputs the programmed jog frequency to the motor. To enable the Run key on the digital operator for jog input, set the value 01(terminal mode) in A002 (Run command source).

No jogging operation is performed when the set

value of jogging frequency A038 is smaller than the start frequency B082, or the value is 0 Hz.

Be sure to stop the motor when switching the function [JG] ON or OFF.
