Function 
Code
Parameter Name Function Description Setting Range Default
b1.01
Slip compensation For SVC, it is used to adjust the speed stability 
accuracy of the motor. When the motor with heavy 
load runs at too low speed, increase the value of 
this parameter. When the motor with heavy load 
runs at too high speed, decrease the value of this 
parameter. 
50.0% to 
200.0%
100.0%
b1.02 Max. frequency When the frequency source is AI or high-speed 
pulse, this parameter is the base value for 
calculating the target frequency.
It is used to set the upper limit of the frequency 
output by the AC drive at any time.
50.00 to 
150.00 Hz
50.00 Hz
b1.03 Min. frequency It is used to set the lower limit of the frequency 
output by the AC drive at any time.
0.00 to 15.00 
Hz
0.00 Hz
b1.04 Forward torque upper 
limit
These two parameters are used to set the output 
torque upper limit when the DI function 1 (forward 
run) and DI function 2 (reverse run 1) are enabled. 
They are the percentage of the rated motor torque. 
In SVC, even if b1.04 and b1.05 are set to lower 
than 50.0%, the AC drive will regard the output 
torque upper limit as 50.0%.
0.0% to 
500.0%
180.0%
b1.05 Reverse torque upper 
limit
0.0% to 
500.0%
180.0%
Group b3: Input/output Parameters
b3.01 DI1 function selection 1. Forward run
2. Reverse run  
The terminal is used to control forward or reverse 
run of the AC drive.
3. Fault reset
The terminal is used for the fault reset function, 
which is the same as the function of RESET key 
on the operation panel. Remote fault reset is 
implemented through this function.
4. Quick stop
If the terminal set for this function becomes ON, 
the AC drive immediately outputs the brake apply 
frequency (b6.05) and executes the brake apply 
time sequence.
5. Coast to stop
If the terminal set for this function becomes ON, the 
AC drive stops the output, the motor coasts to stop 
without control by the AC drive. It is the same as 
coast to stop described in b4.03.
6. Decelerate to stop
If the terminal set for this function becomes ON, the 
AC drive stops according to normal deceleration 
logic. It is the same as canceling the running 
command.
If the 
hundred's digit 
= 1, it indicates 
that the 
function logic 
is reversed. 
Unit's digit 
and ten's 
digit: function 
selection
If they are set 
to 0 and 100, 
it indicates 
that they are 
invalid.
