Bit 1 : Prior to PLC scanning procedures, whether the target torque has been
cleared is 0. (This will be written to the TORQ command when the PLC is
On)
Bit 2 : Prior to PLC scanning procedures, whether speed limits in the torque mode
have been cleared is 0. (This will be written to the TORQ command when
the PLC is On)
Example: When using r to write a program,
M0
if we force M0 to be 1, the frequency command will be 20.00 Hz; but when M0 is set
as 0, there will be a different situation.
Case 1: When the 09-33 bit 0 is 0, and M0 is set as 0, the frequency command will
remain at 20.00Hz.
Case 2: When the 09-33 bit 0 is 1, and M0 is set as 0, the frequency command will
change to 0.00Hz
The reason for this is that when the 09-33 bit 0 is 1 prior to PLC scanning
procedures, the frequency will first revert to 0.
When the 09-33 bit 0 is 0, the frequency will not revert to 0.
