5.7 H: Terminal Functions
Setting 16: Motor 2 selection
The drive has the capability to control two induction motors independently. A second motor may be selected using a
multi-function digital input as shown in
Note: The motor 2 selection function cannot be used when PM motor is used.
Figure 5.17
When switching between motor 1 and motor 2, the parameters used to control those motors also change. Below,
Table 5.11 lists the parameters that correspond to each motor.
No.
C1- : Acceleration/Deceleration Time
E1- , E3- : V/f Pattern
E2- , E4- : Motor Parameters
Note: 1. The drive can switch from motor 2 to operate motor 1 in V/f Control based on the speed reference set for motor 2. Refer to
Switch Selection on page 167
2. It is not possible to switch between motor 1 and motor 2 during run. Doing so will trigger the "rUn" alarm.
3. It is not possible to switch between motors when CLV/PM control mode is selected.
4. The motor 2 selection function is available only with OLV control mode (A1-02 = 0).
5. When switching from motor 1 to motor 2, check to make sure that motor 2 is operating.
If a digital output is programmed for "Motor 2 selection" (H1-01, H1-02, or H1-03 = 1C), motor will be selected when the
output is closed.
Setting 18: Timer function input
This setting configures a digital input terminal as the input for the timer function. Use this setting combination with the
timer function output (H2-

Used to select accel/decel ramps 1 to 4 in combination with the Accel/decel ramp selection 1 command. Refer to
C1-08: Accel, Decel Ramps 1 to 4 on page 154
Setting 20 to 2F: External fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to any value between 20 to 2F. The digital
operator will display EF
For example, if an external fault signal is input to terminal "EF3" will be displayed.,
Select the value to be set in H1-
