n
b1-14: Phase Order Selection
Sets the phase order for drive output terminals U/T1, V/T2, and W/T3. Switching motor phases will reverse the direction
of the motor. Use this parameter to switch the direction of the Up and Down commands.
No.
b1-14
Setting 0: Standard phase order (U-V-W)
Setting 1: Switched phase order (U-W-V)
Note: Make sure that the elevator moves in the correct direction when an Up or Down command is issued.
u b4: Delay Timers
The timer function is independent of drive operation and can delay the switching of a digital output triggered by a digital
input signal and help eliminate chattering switch noise from sensors. An on-delay and off-delay can be set separately.
To enable the timer function, set a multi-function input to Timer input (H1-
Timer output (H2- =12). Only one timer can be used.
n
b4-01, b4-02: Timer Function On-Delay, Off-Delay Time
b4-01 sets the on-delay time for switching the timer output. b4-02 sets the off-delay time for switching the timer output.
No.

Timer Function Operation
The timer function switches on when the timer function input closes for longer than the value set to b4-01. The timer
function switches off when the timer function input is open for longer than the value set to b4-02.
