Setting Value Function Description
3 Multi-Step Speed Reference
1
Uses speed references d1-01 to d1-16 to set a multi-step speed reference.
4 Multi-Step Speed Reference
2
Uses speed references d1-01 to d1-16 to set a multi-step speed reference.
5 Multi-Step Speed Reference
3
Uses speed references d1-01 to d1-16 to set a multi-step speed reference.
6 Jog Reference Selection Sets the drive to use the JOG Frequency Reference (JOG command) set in d1-17. The JOG Frequency Reference (JOG command)
overrides Frequency References 1 to 16 (d1-01 to d1-16).
7 Accel/Decel Time Selection
1
Sets the drive to use Acceleration/Deceleration Time 1 [C1-01, C1-02] or Acceleration/Deceleration Time 2 [C1-03, C1-04].
8 Baseblock Command (N.O.) Sets the command that stops drive output and coasts the motor to stop when the input is ON.
ON : Baseblock (drive output stop)
OFF : Normal operation
9 Baseblock Command (N.C.) Sets the command that stops drive output and coasts the motor to stop when the input terminal is OFF.
ON : Normal operation
OFF : Baseblock (drive output stop)
A Accel/Decel Ramp Hold Momentarily pauses motor acceleration and deceleration when the terminal is turned ON, retains the output frequency that was
stored in the drive at the time of the pause, and restarts motor operation.
B Overheat Alarm (oH2) Sets the drive to show an oH2 [External Overheat (H1-XX=B)] alarm when the input terminal is ON. The alarm does not have an
effect on drive operation.
C Analog Terminal Enable
Selection
Sets the command that enables or disables the terminals selected in H3-14 [Analog Input Terminal Enable Sel].
ON : Input to the terminal selected with H3-14 is enabled
OFF : Input to the terminal selected with H3-14 is disabled
E ASR Integral Reset Sets the command to reset the integral value and use PI control or P control for the speed control loop.
ON : P control
OFF : PI control
F Not Used Use this setting for unused terminals or to use terminals in through mode.
10 Up Command Sets the command to use a push button switch to increase the drive frequency reference. You must also set Setting 11 [Down
Command].
ON : Increases the frequency reference.
OFF : Holds the current frequency reference.
11 Down Command Sets the command to use a push button switch to decrease the drive frequency reference. You must also set Setting 10 [Up
Command].
ON : Decreases the frequency reference.
OFF : Holds the current frequency reference.
12 Forward Jog Sets the command to operate the motor in the forward direction at the Jog Frequency set in d1-17 [Jog Reference].
13 Reverse Jog Sets the command to operate the motor in the reverse direction at the Jog Frequency set in d1-17 [Jog Reference].
14 Fault Reset Sets the command to reset the current fault when the Run command is inactive.
Note:
The drive ignores the fault reset command when the Run command is active. Remove the Run command before trying to reset a
fault.
15
Fast Stop (N.O.) Sets the command to ramp to stop in the deceleration time set in C1-09 [Fast Stop Time] when the input terminal is ON while the
drive is operating.
16 Motor 2 Selection Sets the command for the drive to operate motor 1 or motor 2. Stop the motors before switching.
ON : Operate motor 2
OFF : Operate motor 1
17 Fast Stop (N.C.) Sets the command to ramp to stop in the deceleration time set in C1-09 [Fast Stop Time] when the input terminal is ON while the
drive is operating.
18 Timer Function Sets the command to start the timer function. Use this setting with Timer Output [H2-xx = 12].
19 PID Disable Sets the command to disable PID control when b5-01 = 1 to 8 [PID Mode Setting = Enabled].
ON : PID control disabled
OFF : PID control enabled
1 A Accel/Decel Time Selection
2
Set this function and H1-xx = 7 [Accel/Decel Time Selection 1] together. Sets the drive to use Acceleration/Deceleration Time 3
[C1-05, C1-06] or Acceleration/Deceleration Time 4 [C1-07, C1-08].
1B Programming Lockout Sets the command to prevent parameter changes when the terminal is OFF.
ON : Programming Lockout
OFF : Parameter Write Prohibit
1E Reference Sample Hold Sets the command to sample the frequency reference at terminal A1 or A2, and hold the frequency reference at that frequency.
