Chapter 7 – Control circuit terminal functions

JG: Jogging run
Terminal function
When a digital input configured as JG is activated, then the motor can be driven in jogging mode. This is
useful for example when preparing a machine in manual operation mode. In this case a low frequency
(without the usual acceleration ramp) is sent to the motor when the FW or RV input is activated along with
the JG input.

Configuration
A 02 A 38 A 39 C 01 – C 05
1) Configure A 38 first to set the frequency that is to be sent to the motor when jogging mode is activated.
Please remember not to use a too high frequency since the frequency is directly sent to the motor without
an acceleration ramp which may lead to a trip. You should set a frequency that is less than 5Hz.
2) Since in jogging mode the running command is issued using inputs FW or RV you have to set A 02 to
01.
3) A 39 determines the way the motor decelerates. The parameters 00 (free run stop, this is the default), 01
(deceleration using deceleration ramp) and 02 (deceleration using DC braking) are available.
4) Configure one of the digital inputs 1 – 5 as JG input by entering the parameter 06 under C 01 – C 05 .
CAUTION Please make shure that the motor has completely stopped before activating the JG
input.
Remarks
•
The jogging mode can not be executed when the jogging frequency set under A 38 is less than the start
frequency set under b 82 .
•
The jogging mode can only be activated when the motor has stopped.
