Parameter Name Function Description Setting Range Default
Group b5: Multi-speed Parameters
b5.00 Upward multi-speed  1 The multi-speed function is implemented by state 
combinations of DI terminals that are set for 
functions 8 and 9. The combinations are shown as 
follows:
Input Function 9 Input Function 8 Target Speed
OFF OFF b5.00
OFF ON b5.01
ON OFF b5.02
ON ON b5.03
When b7.01 = 1, the following four speeds are 
used. The corresponding relationship is as follows:
Input Function 9 Input Function 8 Target Speed
OFF OFF b5.04
OFF ON b5.05
ON OFF b5.06
ON ON b5.07

Group b6: Brake Logic Control Parameters
b6.01 Start direction It is used to set the direction of the AC drive output 
torque within the brake release time.

b6.02 Brake release 
frequency in the 
upward direction
It is used to set the AC drive output frequency 
before the brake releases completely, namely, the 
minimum frequency, at which the motor can output 
full torque.
