This parameter is used to set the low voltage level. When the drive is in a low input voltage sag,
the drive will coast the motor to a stop. The drive will start the motor again once the input voltage
reaches 30 volts higher than P6.35 for 230V inputs, and 60V higher for 460V inputs.

P6.36 OC Stall Prevention Accel/Decel Time Selection at Normal Speed
♦R/W 0624 41573
Range/Units (Format: 16-bit binary) Default
1: Follow the 1st Accel/Decel Time
2: Follow the 2nd Accel/Decel Time
3: Follow the 3rd Accel/Decel Time
4: Follow the 4th Accel/Decel Time
5: Auto Accel/Decel
0
Used to follow the Accel/Decel Time Selection (P1.01~1.08) when Over-Current Stall prevention
(P6.21) occurs at normal speed.

P6.37 OC Stall Prevention Limit for Operation Over Rated Speed
♦R/W 0625 41574
Range/Units (Format: 16-bit unsigned) Default
0~100%
50
This parameter is used when operation frequency is greater than P0.02 and P0.13 Motor Base
Frequency.
Example: When P6.20=150%, P6.21=100%, and P6.37=80%, then:
•
Stall Prevention Level during Accel over motor base frequency = P6�20 x P6�37 = 150% x 80%
=120%�
•
Stall Prevention Level at constant speed over motor base frequency = P6�21 x P6�37 = 100% x 80%
= 80%�

P6.38 Torque Limit (Current Limit)
♦R/W 0626 41575
Range/Units (Format: 16-bit unsigned) Default
0~200% (of drive’s rated current)
150
This parameter sets the maximum current output of the drive.
