1: 共模(带低速补偿)
因为普通电机的冷却效果恶化
低速(低于30Hz)时,电机过热
应降低保护阈值,这称为
低速补偿。
2: 变频电机(无低速
补偿)
变频电机的冷却效果不是
受电机速度的影响,所以速度较低
不需要补偿。

to-tuning. You can also give up the auto-tuning. At this
time, please input the values on the motor’s nameplate
correctly (FH.00~FH.02).
If the auto-tuning cannot be applied and the correct motor’s
parameters are available, the user should input the values
on the motor’s nameplate correctly (FH.00~FH.02), and
then input the calculated values (FH.03~FH.07). Be sure to
set the parameters correctly.
If auto-tuning is not successful, the drive will alarm and
display fault code E024.
FH.10 Motor’s stabilization
factor
Range:0~255【dependent
on drive’s model】
FH.10 is used to suppress the oscillation caused by the
drive and the motor. If the drive’s output current changes
frequently at constant load, you can reduce the
oscillation by adjusting the parameter.
For the drive of 55kW or below, FH.10 is set at 10, and
“20” for the drive of 55kW or above.

5.14 Protective Function (Group FL)
FL.00 Motor overload
protection mode selection Range:0. 1. 2【1】
0: Disabled
The overload protection is disabled. Be careful to use
this function because the drive will not protect the motor
when overload occurs;
Chapter 5 Parameter Introductions 79
EV2000 Series Universal Variable Speed Drive User Manual
1:Common mode (with low speed compensation)
Since the cooling effects of common motor deteriorates
at low speed (below 30Hz), the motor’s overheat
protecting threshold should be lowered, which is called
low speed compensation.
2: Variable frequency motor (without low speed
compensation)
The cooling effects of variable frequency motor is not
affected by the motor’s speed, so low speed
compensation is not necessary.
FL.01 Motor’s overload
protection coefficient
Range:20.0~110.0%
【100.0%】
In order to apply effective overload protection to different
kinds of motors, the Max output current of the drive
should be adjusted as shown in Fig. 5-71.

Use the following coefficient to calculate the coefficient:

Generally, the Max load current is the motor’s rated
current.
Note:
If the motor’s rated current does not match that of the drive,
motor’s overload protection can be realized by setting
FL.00~FL.01.

Range:120~150%
【140.0%】
0: Disabled
1: Enabled
During deceleration, the motor’s decelerate rate may be
lower than that of drive’s output frequency due to the
load inertia. At this time, the motor will feed the energy
back to the drive, resulting in the voltage rise on the
drive's DC bus. If no measures taken, the drive will trip
due to over voltage.
During the deceleration, the drive detects the bus
voltage and compares it with the over voltage point at
stall defined by FL.03. If the bus voltage exceeds the
stall overvoltage point, the drive will stop reducing its
output frequency. When the bus voltage become lower
than the point, the deceleration continues, as shown in
Fig. 5-72.

Note:
The drive will alarm and display E015 when it is in the

If the stall point is set too low, you can prolong the Acc and
Dec time properly.

EV2000 has protection over drive and motor overload.
See Table 2-1 for drive overload protection, and FL.00
and FL.01 for motor overload protection. FL.04~FL.06
can monitor the overload condition before overload
protection happens.
