Note
• Inching operation (JOG determination time)
To perform inching operation, specify the JOG determination time.
- If the forward/reverse JOG activation time is within the JOG command determination time, a pulse string
equivalent to
±
1 (user unit) is output at the current address to operate the inching.
- If the forward/reverse rotation JOG activation time is equal to or larger than the JOG command
determination time, pulse strings are output continuously.
- If the JOG command determination time is 0ms, the travel equivalent to
±
1 at the current address (user)
is not executed. Continuous operation is executed from the first point.
• If the simultaneous START flag turns ON, the simultaneous JOG operation in the X- and Y-axes starts at
an X-axis JOG command.(The Y-axis JOG command is ignored.)
At the X-axis JOG command OFF, the 20SSC-H stops the X and Y-axes JOG operation.
8.2.2
Changing the speed during JOG operation
When changing the jog speed during jog operation, use the operation speed change function or override
setting. If the jog speed is changed using the positioning parameters, the jog speed will not be changed
during the current jog operation.
When changing positioning parameters
Even if the positioning parameters are changed (updated), the jog operation speed will not be changed during
the current jog operation. The system will adopt the changed jog speed from a jog operation started after the
jog speed change. For enabling the jog speed (positioning parameters) changed in a sequence program, it is
necessary to set to ON from OFF the positioning parameter enable command.
Accordingly, when changing the jog speed during operation, use the operation speed change function or
override setting.
