2: Dec-to-stop+DC injection braking
After receiving the STOP command, the drive reduces
its output frequency according to the Dec time and starts
DC injection braking when its output frequency reaches
the initial frequency of braking process.
Refer to the introductions of F2.09~F2.12 for the
functions of DC injection braking.

DC injection braking waiting time at stop: The duration
from the time when operating frequency reaches the DC
injection braking initial frequency(F2.09) to the time
when the DC injection braking is applied.
The drive has no output during the waiting time. By
setting waiting time, the current overshoot in the initial
stage of braking can be reduced when the drive drives a
high power motor.
The range of DC injection braking current and time are
dependent on drive’s model, see Table 5-2.
DC injection braking current at stop is a percentage of
drive’s rated current. There is no DC injection braking
when the braking time is 0.0s.

Note:

F2.13 Dynamic braking Range:0,1【0】
0: Dynamic braking is disabled
1: Dynamic braking is enabled
Note:
This parameter must be set correctly according to the actual
conditions, otherwise the control performance may be
affected.

This function is effective for the drive with built-in braking
resistor.
Note:
Resistance and power of the braking resistor must be taken
into consideration when setting this parameters.

50 Chapter 5 Parameter Introductions
EV2000 Series Universal Variable Speed Drive User Manual
When the motor operates without load or with light load,
the drive can adjust its output voltage by detecting the
load current to achieve the energy-saving effects.
Note:
This function is especially useful for the fan & pump loads.
F3.06 AVR function Range:0. 1. 2【2】
0:disabled
1: enabled all the time
2: disabled in Dec process
AVR means automatic voltage regulation.
The function can regulate the output voltage and make it
constant. Therefore, generally AVR function should be
enabled, especially when the input voltage is higher than
the rated voltage.
In Dec-to-stop process, if AVR function is disabled, the
Dec time is short but the operating current is big. If AVR
function is enabled all the time, the motor decelerates
steadily, the operating current is small but the Dec time
is prolonged.
F3.07 Gain of slip
compensation Range:0.0~300.0%【100.0%】
F3.08 Limit of slip
compensation Range:0.0~250.0%【200.0%】
F3.09 Compensation
time constant Range:0.1~25.0s【2.0s】
The motor’s slip changes with the load torque, which
results in the variance of motor speed. The drive’s
output frequency can be adjusted automatically through
slip compensation according to the load torque.
Therefore the change of speed due to the load change
is reduced as shown in Fig. 5-18.

Motoring status: Increase the gain of slip compensation
gradually when the actual speed is lower than the
reference speed (F3.07).
Regenerating status: Increase the gain of slip
compensation gradually when the actual speed is higher
than the reference speed (F3.07).
Range of slip compensation: limit of slip
compensation(F3.08) × rated slip(FH.08)
Note:
The value of automatically compensated slip is dependent
on the motor’s rated slip, therefore the motor’s rated slip
must be set correctly (FH.08).
