Restrictions
• A manual pulse generator is required to perform the manual pulse generator operation.
• Do not use manual pulse generator operation when another axis is in pre-analysis mode. This is because pulses may be
output at unintended timings for axes subject to manual pulse generator operation.
Precautions during the operation
The following details must be understood before performing the manual pulse generator operation.
• The speed during the manual pulse generator operation is not limited with [Pr.8] Speed limit value. For this reason,
configure [Cd.20] Manual pulse generator 1 pulse input magnification such that the output command frequency is
200 kpulse/s or less.
• If [Cd.21] Manual pulse generator enable flag is turned on while the positioning module is busy (BUSY signal is on), Start
during operation (Warning code: 0900H) occurs.
• If a stop factor occurs during the manual pulse generator operation, the operation stops and BUSY signal turns off. At this
time, [Cd.21] Manual pulse generator enable flag remains on, but the manual pulse generator operation cannot be
performed. To perform the manual pulse generator operation again, take measures to eliminate the stop factor and turn off
and on [Cd.21] Manual pulse generator enable flag. (Note that this excludes when a hardware/software stroke limit error
occurs.)
• Pulses are not output if an error occurs when the manual pulse generator operation is started.
• One positioning module can be connected to one manual pulse generator.
• The positioning module can simultaneously output pulses to axis 1 and axis 2 drive units using one manual
pulse generator. (1/2 axis simultaneous operation is possible.)
Operation when a stroke limit error occurs
When a hardware stroke limit error or a software stroke limit error is detected during the operation
performed. However, the status of [Md.26] Axis operation status remains in Manual pulse generator operation
After the operation has stopped, the manual pulse generator input pulses in the direction toward outside the limit range are
not accepted, but the operation in the direction toward the range can be executed.
*1 Only when the current feed value or the machine feed value overflows or underflows during the deceleration, the status of [Md.26] Axis
operation status is changed to Error and the manual pulse generator operation terminates. To perform the manual pulse generator
operation again, turn off [Cd.21] Manual pulse generator enable flag once and turn on.
