(2) Precautions during operation
(a) Acceleration/deceleration processing during inching operation
Acceleration/deceleration processing is not carried out during inching operation.
(Pulses corresponding to the designated inching movement amount are output at 1.8ms. The movement
direction of inching operation is reversed and, when backlash compensation is carried out, first pulses
corresponding to the backlash amount are output at 1.8ms and then pulses corresponding to the designated
inching movement amount are output in the next 1.8ms.)
The "[Cd.17] JOG speed" is ignored even if it is set. However, the error "Inching movement amount error" (error
code: 301) will occur in the following cases:
• ([Cd.16] Inching movement amount) (A) > ([Pr.31] JOG speed limit value)
Where (A) is as follows.
• When the unit is pulse: 562.5
• When the unit is other than pulse: 337.5
(b) Setting of "[Cd.16] Inching movement amount"
Set a value other than a "0" in "[Cd.16] Inching movement amount".
If a "0" is set, the operation will become JOG operation. ( Page 481, Section 11.2)
(3) Operations when stroke limit error occurs
When the operation is stopped by hardware stroke limit error or software stroke limit error, the inching operation
can be performed in an opposite way (direction within normal limits) after an error reset. (An error will occur again
if JOG start signal is turned ON in a direction to outside the stroke limit.)
