5 MANUAL CONTROL
5.3 Inching Operation
Precautions during the operation
• The inching operation does not perform acceleration/deceleration processing. (Pulses for the specified inching movement
amount are output at 1.77ms. The direction of the inching operation is reversed. When the backlash compensation is
performed, pulses for the backlash are output at 1.77ms and pulses for the specified inching movement amount are output
at the next 1.77ms.) [Cd.17] JOG speed is ignored even if it is set. However, Inching movement amount error (Error code:
1981H) occurs in the following cases.
• Set a value other than 0 for [Cd.16] Inching movement amount. When 0 is set, the JOG operation is performed. (  Page
176 JOG Operation)
Operation when a stroke limit error occurs
When the operation is stopped due to a hardware stroke limit error or software stroke limit error during the operation, the
inching operation can be operated in the opposite direction (direction toward the normal range) after the error is reset. (If JOG
start signal is turned on in the direction toward outside the limit range, the error occurs again.)
