12.8 H: Terminal Function Selection
YASKAWA SIEPC71061753C GA500 Technical Manual 631
WARNING! Sudden Movement Hazard. When you use a mechanical holding brake with the drive in a lifting application, you
must close the brake if an input terminal triggers the Baseblock command to stop drive output. If you enter the baseblock
command, the motor will suddenly coast and the load will slip, which can cause serious injury or death.
WARNING! Incorrect Operation. Yaskawa recommends that you use H1-xx = 9 [Baseblock Command (N.C.)]. If a circuit error
occurs in the MFDI, the drive cannot stop the output when the terminal set to H1-xx = 8 [Baseblock Command (N.O.)] turns ON.
The keypad flashes bb [Baseblock]. If you cancel the baseblock command when the Run command is active, the
drive will restart the motor and use the speed search function.

9 Baseblock Command (N.
C.)
Sets the command that stops drive output and coasts the motor to stop when the input terminal is OFF.
The keypad flashes bb [Baseblock]. If you cancel the baseblock command when the Run command is active, the
drive will restart the motor and use the speed search function.

OFF : Baseblock (drive output stop)
WARNING! Sudden Movement Hazard. When you use a mechanical holding brake with the drive in a lifting application, you
must close the brake if an input terminal triggers the Baseblock command to stop drive output. If you enter the baseblock
command, the motor will suddenly coast and the load will slip, which can cause serious injury or death.
■ A: Accel/Decel Ramp Hold
Setting Value Function Description
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.
If the terminal is deactivated, the drive restarts acceleration and deceleration.
When the acceleration/deceleration ramp hold terminal is activated and d4-01 = 1 [Freq Reference Retention
Select = Enabled], the drive will store the output frequency in memory. While the acceleration/deceleration ramp
hold command is activated, the drive will always restart the motor at this output frequency.
Note:
Refer to d4-01: Freq Reference Hold Selection on page 574 for more information.
■ B: Overheat Alarm (oH2)
Setting Value Function Description
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
Setting Value Function Description
C Analog Terminal Enable
Selection
Sets the command that enables or disables the terminals selected in H3-14 [Analog Input Terminal Enable Sel].
