Chapter 16 PLC Function ApplicationsMH300
bit 1: Prior to PLC scanning procedures, acts on whether the target torque has
been cleared to 0. This is written to the TORQ command when the PLC is
On.
bit 2: Prior to PLC scanning procedures, acts on whether speed limits in the torque
mode have been cleared to 0. This is written to the TORQ command when
the PLC is On.
Example: When using r to write a program,
If we force M0 to 1, the frequency command is 20.00 Hz; but when M0 is set to 0,
there is a different situation.
Case 1: When the Pr.09-33 bit 0 is 0, and M0 is set as 0, then the frequency
command remains at 20.00 Hz.
Case 2: When the Pr.09-33 bit 0 is 1, and M0 is set as 0, then the frequency
command changes to 0.00 Hz
This is because when Pr.09-33 bit 0 is 1 prior to PLC scanning procedures, the
frequency first reverts to 0. When Pr.09-33 bit 0 is 0, the frequency does not revert
to 0.
