11 MANUAL CONTROL
Precautions during operation
The following details must be understood before inching operation is carried out.
(1) Acceleration/deceleration processing is not carried out during inching
operation.
(Pulses corresponding to the designated inching movement amount are output
at the first control cycle of the QD75 (3.5 ms). The movement direction of
inching operation is reversed and, when a backlash compensation is carried
out, first pulses corresponding to the backlash amount are output in the first
control cycle of the QD75 and then pulses corresponding to the designated
inching movement amount are output in the subsequent control cycles.)
The "
Cd.17
JOG speed" is ignored even if it is set. An error will occur in the
following cases (error code: 301).
(
Cd.16
Inching movement amount) x (A) > (
Pr.31
JOG speed limit value)
Where (A) is as follows.
• When the unit is PLS: 281.25
• When the unit is other than PLS: 168.75
(2) JOG start signal OFF ON immediately after stop signal ON OFF (within
100 ms) is ignored.
(Operation will not start.)
(3) Set a value other than a "0" in "
Cd.16
Inching movement amount".
If a "0" is set, the operation will become JOG operation (Refer to Section 11.2
"JOG operation").
Errors during operation
When the operation is stopped by the stroke limit (limit signal OFF), inching
operation can be performed out in the direction in which the limit signal turns ON
after an error reset.
(JOG start signals in the direction in which the limit signal turns OFF will be
ignored.)
