4.5.1 Fixed speed in JOG mode
Four fixed speeds can be used in JOG mode. The fixed speed to be used can be
selected via parameter
Reference Frequency Source 475 of the reference frequency
channel. For parameter
Reference Frequency Source 475, an operation mode with
fixed speed (FF/fixed frequency) must be selected. Via the logic states of the signals
assigned to parameters
Fixed Frequency Change-Over 1 66 and Fixed Frequency
Change-Over 2
67, one of the four fixed speeds can be selected. Parameters Fixed
Frequency Change-Over 1
66 and Fixed Frequency Change-Over 2 67 must be
assigned digital input signals or logic signals (factory setting: digital inputs EM-S1IND
and EM-S2IND of an optional extension module).

Selection of fixed speed for JOG mode:
•
Set one or several of parameters
Fixed Speed 1 1170 to Fixed Speed 4 1173.
• Assign digital inputs or logic signals to parameters 66 and
Fixed Frequency
Change-Over 2
67. Via the logic states of the input signals, select a fixed speed.
• For parameter
Reference Frequency Source 475, set an operation mode with
fixed speed (FF), e.g. "10 – Abs. Val. Fixed Frequency (FF)".
When a digital signal is present for
Jog Mode Active 1231 and Jog Clockwise 1232
or
Jog Anticlockwise 1233, the drive moves at the selected speed.
