Shenzhen Hpmont Technology Co., Ltd. Chapter 7 Detailed Function Introduction
HD09 Series User Manual V1.1 -49-
vervoltage stall function (F19.18, F19.19)
Ref. Code Function Description Setting Range [Default]
F19.18 Overvoltage stall selection 0,1 [1]
0: No. This condition is recommended to install the braking resistor.
1: Allow. During the slowdown of the inverter, the bus voltage is compared with F19.19.
• If the detected bus voltage exceeds F19.19, the inverter output frequency will stop falling and be
detected again. If the bus voltage is lower than F19.19, the inverter will continue to slow down.
Note: When the overvoltage stall condition is held for more than 1 minute, the inverter reports an overvoltage stall
failure (E0007) and stops the output.
F19.19 Overvoltage speed lose point 0 - 999V [Type confirmed]
current limit function (F19.20 - F19.22)
Ref. Code Function Description Setting Range [Default]
Automatic current limit selection
0: Invalid.
1: Effective acceleration and deceleration, constant speed is invalid.
2: Deceleration, constant speed are effective.
Automatic current limit level
The current threshold for the automatic current limiting operation is defined as the percentage relative to the
rated current of the drive.
• If the F19.21 setting is low when the automatic current limit is active, the inverter overload capacity may
be affected.
Automatic current limit deceleration time
Defines the rate at which the output frequency is adjusted when the automatic current limiting action is
performed.
• If the setting is too large, it may be in an automatic current limit for a long time to cause an overload fault.
• When the setting is too small, the frequency adjustment will increase, which may cause the inverter to be
over-voltage protected for a long time.
• When F19.22 = 0, the current limit does not slow down.
