16: Motor 2 Selection

Setting Value

Function

Description

16

Motor 2 Selection

Sets the command for the drive to operate motor 1 or motor 2. Stop the motors before switching.

You can use an external input to switch operation between two induction motors. The drive will save the control methods, V/f patterns, and motor parameters for the two motors.

ON
Selects motor 2
 
OFF
Selects motor 1
 

When you select motor 2, the drive will switch to motor 2 parameters.

Note:

  • When you use 2 motors, the drive applies the protective function set in L1-01 [Motor Overload (oL1) Protection] to motor 1 and motor 2.

  • You cannot switch between motors 1 and 2 during run. If you try to switch motors when they are running, it will cause a rUn [Motor Switch during Run] error.

  • After you switch between encoder motors, you must wait 500 ms minimum to input a Run command. You must wait 200 ms minimum for other control methods.

  • If you set H1-xx = 16 [Motor 2 Selection] and set different control methods in maximum output frequency to motors 1 and 2, the drive will apply the lower of the two maximum to the two motors. The upper limit of d1-xx [Frequency Reference] will change. For example, the upper limit of d1-xx will be 400 when you set these parameters to these values:

    • A1-02 = 2 [Control Method Selection = OLV]

    • E1-04 = 590 [Maximum Output Frequency = 590 Hz]

    • E3-01 = 3 [Motor 2 Control Mode Selection = CLV]

    • E3-04 = 400 [Motor 2 Maximum Output Frequency = 400 Hz]
