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 QD70D 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.)
Setting value
Set the speed for JOG
5000pulse/s
operation.
Set the acceleration time
1000ms
for JOG operation.
Set the deceleration time
1000ms
for JOG operation.
0: Forward run JOG
Set the rotation direction
1: Reverse run JOG
for JOG operation.
(3) Reciprocating operation program using JOG operation
The following is a program example for Axis 1.
(When the QD70D is installed in slot 0 of the main base unit)
