YASKAWA ELECTRIC SIEP YEAHHP 01B YASKAWA AC Drive – A1000 HHP Programming Manual
Description
All Modes
Sets the action for when a thermistor open circuit is detected.
0: Ramp stop
1: Coast stop
2: Fast Stop (decelerate to stop using the deceleration time set to C1-09)
3: Alarm, Continue Running
All Modes
Sets the action for when a oH5 is detected in either Motor #1 or Motor #2.
0: Ramp stop
1: Coast stop
2: Fast Stop (decelerate to stop using the deceleration time set to C1-09)
3: Alarm, Continue Running
All Modes
Sets the type of thermistor input for Motor #1 and Motor #2: either NTC or
Pt100.
0: H5 table selection
1: Pt100 table selection
Description
All Modes
0: Disabled. Drive trips on Uv1 fault when power is lost.
1: Recover within the time set in L2-02. Uv1 will be detected if power loss is
longer than L2-02.
2: Recover as long as CPU has power. Uv1 is not detected.
3: KEB deceleration for the time set to L2-02.
4: KEB deceleration as long as CPU has power.
5: KEB deceleration to stop.
All Modes
Sets the Power Loss Ride-Thru time. Enabled only when L2-01 = 1 or 3.
All Modes
Sets the minimum wait time for residual motor voltage decay before the drive
output reenergizes after performing Power Loss Ride-Thru.
Increasing the time set to L2-03 may help if overcurrent or overvoltage occur
during Speed Search or during DC Injection Braking.

Sets the time for the output voltage to return to the preset V/f pattern during
Speed Search.
All Modes
Sets the DC bus undervoltage trip level.
All Modes
Sets the time to accelerate to the frequency reference when momentary power
loss is over. If set to 0.0, the active acceleration time is used.
All Modes
Sets the time to perform KEB Ride-Thru.
All Modes
Sets the desired value of the DC bus voltage during KEB Ride-Thru.
