Setting 16: Motor 2 Selection
The drive has the capability to control two induction motors independently. A second motor may be selected using a
contact input as shown in
Figure 2.48
When switching between motor 1 and motor 2, the parameters used to control those motors also change. Below,
Table 2.23 lists the parameters that correspond to each motor.
No.
C1- : Acceleration/Deceleration Time C1-01 to C1-04
C3- : Motor Slip Compensation
C4- : Motor Torque Compensation
C5- : Speed Control (ASR)
E1- , E3 : V/f Pattern
E2- , E4 : Motor Parameters
F1- (PG Constant)
Note: 1. When using 2 motors, the motor overload protection selection (oL1) set to L1-01 applies to both motor 1 and motor 2.
2. It is not possible to switch between motor 1 and motor 2 during run. Doing so will trigger the "rUn" alarm.
3. There is a 500 ms delay when switching between motors equipped with a PG encoder for feedback.
If a contact 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 contact input terminal as the input for the timer function. Use this setting in combination with
the timer function output (H2-
Setting 19: PID Disable
When the PID function has been enabled by parameter b5-01, it can be indefinitely disabled by closing a contact input.
When the input is released, the drive resumes PID operation. Also refer to
Setting 1A: Accel/decel Time Selection 2
Selects accel/decel times 1 to 4 in combination with the Accel/decel time selection 1 command. Refer to
Accel, Decel Times 1 to 4 on page 128
Setting 1B: Program Lockout
When an input is programmed for Program Lockout, parameter values cannot be changed as long as this input is open (it
is still possible to view and monitor parameter settings).
Setting 1E: Reference Sample Hold
This function allows the user to sample an analog frequency reference signal being input to analog input 1 or analog
input 2 and hold the frequency reference at the sampled level. When the Analog Frequency Reference Sample/Hold
function is held for at least 100 ms, the drive reads the analog input and changes the frequency reference to the newly
sampled speed as illustrated in
When the power is shut off and the sampled analog frequency reference is cleared, the frequency reference is reset to 0.
