Jogging Stop Selection
Note: To perform the jogging operation, turn on the JG terminal before the FW or RV terminal.
(Do the same if the RUN command source is set to the Digital Operator.)
Torque Boost
• Compensates for the voltage drop caused by the primary resistance of the motor, or by wiring to
suppress torque reduction at a low speed range.
• To select the automatic torque boost for A041/A241, set motor capacity selection H003/H203 and
motor pole number selection H004/H204 according to your motor.
(Example 1) (Example 2)
With jogging stop selection A039 set to "00", "01", or
"02", jogging does not function if the FW signal is turned
on first. With A039 set to "03", "04", or "05", jogging functions even
if the FW signal is turned on first. However, if the JG signal
is turned off before the FW signal, the motor coasts to a free
running stop.
