Pulse Output Stop - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Pulse output stop

The following table lists methods to stop pulse output, other than normal completion.
Select the stop method according to whether to use deceleration (deceleration stop or immediate stop) and to use the
remaining distance operation. (Page 39 Remaining distance operation)

*1 The PLSY/DPLSY instruction is stopped immediately by all the operations.
*2 Only the FX5 specified abnormal end flag is valid.
Precautions
• Note that the immediate stop may damage the machine because the motor stops immediately.
• Pulse output stop takes priority over deceleration stop. Pulse outputs are immediately stopped if an immediate stop
operation is performed during a deceleration stop operation.

Remarks
Immediate stop without any conditions
Immediate stop without any conditions
With the corresponding instruction, the remaining
distance operation can be used.
For remaining distance operation-compatible
instructions (when the remaining distance operation
is enabled), the PLSV/DPLSV instruction (when
unlimited pulses are output), and table operation
instruction (control method: [4: Variable Speed
Operation] or [5: Table Transition Variable Speed
Operation]), the abnormal end flag does not turn on.
Effective only at forward rotation
Effective only at reverse rotation
Immediate stop if a stop processing fails during
pulse output due to a bus error
Only high-speed pulse input/output module is
supported.
Deceleration stop without any conditions
For the PLSY/DPLSY instruction, the PLSV/DPLSV
instruction and table operation instruction (control
method: [4: Variable Speed Operation] or [5: Table
Transition Variable Speed Operation]), the abnormal
end flag does not turn on.
When the command speed is changed, pulse output
is restarted.
