5 SETUP AND PROCEDURES BEFORE OPERATION
5.7 Simple reciprocating operation
Before operating the system, check the operation of the drive unit.
(Make this check after making sure that the installation, wiring, intelligent function
module switch setting and connection confirmation of the QD70 are normal. For details
of the drive unit, refer to the manual of the drive unit used.)
The following is the way to perform "simple reciprocating operation".
(1) Operation method
Using a sequence program, perform forward run/reverse run of JOG operation.
(Refer to Chapter 10 for details of JOG operation.)
(2) Setting items
Set JOG data in the sequence program. The other data (parameters, positioning
data, etc.) may be initial values.
(Change the JOG data setting values according to the machine specifications.)
