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 Figure 5.17.
Note: The m otor 2 selection function cannot be used w hen PM m otor is used.

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.

Note: 1. The drive can switch from m otor 2 to operate motor 1 in V /f Control based on the speed reference set for m otor 2. R efer to M o to r
Switch Selection on page 155 for details.
2. It is not possible to switch between motor 1 and m otor 2 during run. D oing so will trigger the “rU n” alarm.
3. It is not possible to switch betw een motors when CLV/PM control mode is selected.
4. The m otor 2 selection function is available only w ith OLV control mode (A1-02 = 0).
5. W hen switching from m otor 1 to m otor 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: Tim er 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-DD = 12). Refer to b4: Delay Timers on page 142 for details.
Setting 1A: Accel/decel ramp selection 2
Used to select accel/decel ramps 1 to 4 in combination with the Accel/decel ramp selection 1 command. Refer to C1-01
to C1-08: Accel, Decel Ramps 1 to 4 on page 144 for details.
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 EFD where □ is the number o f the terminal to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal “EF3” will be displayed.,
Select the value to be set in H 1-D D from a combination o f any o f the following three conditions:
• Signal input level from peripheral devices (N.O., N.C.)
• External fault detection method
• Operation after external fault detection
