9.3.2 Inching Operation
This is a kind of manual operation and executing positioning at the speed already set on manual operation
parameter as much as the amount of movement already set on the data of inching operation command.
(1) Characteristics of Control
(a) While the operation by ON/OFF of Jog signal is difficult in moving to the correct position as the operation
starts and stops according to the command, the inching command enables to set the desired transfer
amount easily and reach the goal point.
(b) Thus, it is available to reach the correct goal position by moving fast near the working position by Jog
command and operating the detail movement by inching command.
(c) The setting range is
–2147483648 ∼
2147483647 Pulse.
(d) The direction of moving depends on the amount of inching.
■ The amount is PO) : Positioning operation in forward direction
■ The amount is NEGATIVE(-) : Positioning operation in reverse direction
(e) Acc./Dec process and Inching speed
Use Jog acc./dec. Time of manual operation as acc./dec. time of Inching operation.
Set Jog acc./dec. time on “Jog acc./dec. time” of manual operation parameter setting of XG-PM.
Set Inching speed on “Inching speed” of manual operation parameter setting.
If inching speed is set out of the setting range, error will occur and the operation does not work.
■ Related parameter setting (Manual operation parameter)
