Chapter 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.
(Commands corresponding to the designated inching movement amount are
output at operation cycle. When the movement direction of inching operation
is reversed and backlash compensation is carried out, the backlash
compensation amount and inching movement amount are output at the same
operation cycle.)
The "[Cd.17] JOG speed" is ignored even if it is set. The error "Inching
movement amount error" (error code: 301) will occur in the following cases.
([Cd.16] Inching movement amount) x (A) > ([Pr.31] JOG speed limit value)
However, (A) is as follows.
[RJ010 mode] Unit: [ms]
Operation cycle
0.88 1.77 3.55
When unit is set to PLS 1125 562.5 281.25
When unit is set to degree and "[Pr.83] Speed control
10 x multiplier setting for degree axis" is valid
67.5 33.75 16.88
When unit setting is other than the above 675 337.5 168.75
[CiA402 mode] Unit: [ms]
Operation cycle
1.00 2.00 4.00
When unit is set to PLS 1000 500 250
When unit is set to degree and "[Pr.83] Speed control
10 x multiplier setting for degree axis" is valid
60 30 15
When unit setting is other than the above 600 300 150
(2) 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").
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.)
