Phase Order Selection
Sets the phase order for output terminals U/T1, V/T2, and W/T3. This parameter can align the
Forward Run command from the drive and the forward direction of the motor without changing

b4: Timer Function
The drive uses timers to delay activating and deactivating MFDO terminals.
Timers prevent sensors and switches from making chattering noise.
There are two types of timers:
• Timers that set a delay for timer inputs and timer outputs.
These timers delay activating and deactivating of the MFDIs and MFDOs.
To enable this function, set
H1-xx = 18 [MFDI Function Selection = Timer Function], and set H2-01 to H2-03
= 12 [MFDO Function Selection = Timer Output] .
•
Timers that set a delay to activate and deactivate MFDO terminals.
These timers delay activating and deactivating MFDO terminals.
To enable this function, set delay times in parameters
b4-03 to b4-08 .
■
Timer Function Operation
• Timers that Set a Delay for Timer Inputs and Timer Outputs
Triggers timer output if the timer input is active for longer than the time set in
b4-01 [Timer Function ON-Delay
Time] . Triggers timer output late for the time set in b4-02 [Timer Function OFF-Delay Time] . Figure 12.1
shows an example of how the timer function works.
