EV2000 Series Universal Variable Speed Drive    User Manual 
Use terminals FWD, REV, JOGF and JOGR to start and 
stop the drive. 
2: Serial port control: Input commands via serial port 
Use serial port to start and stop the drive. 
 Notes 
Please be careful that during operating, the control modes 
can be changed through F0.03 or external terminals or 
PANEL/REMOTE key. 
F0.04 Set running direction 
Range: 0, 1  【0】 
This function is active in panel control mode and serial 
port control mode, and inactive in terminal control mode. 
0: Forward 
1: Reverse 
F0.05 Max output

Range: Max{50.00,F0.12 upper 
limit of frequency}~650.00Hz

Range:1~480V  【drive’s rating 
values】 
Max output frequency is the highest permissible output 
frequency of the drive, as shown in Fig. 5-2 as f
max
; 
Basic operating frequency is the Min frequency when 
the drive outputs the max voltage, as shown in Fig. 5-2 
as f

Fig. 5-2 Characteristic parameters 
The f

 and f

 are defined by F0.12 and F0.13 as upper 
limit of frequency and lower limit of frequency 
respectively. 
 Note: 
Please set fmax, fb and Vmax according to motor 
parameters, otherwise the equipment may be damaged. 
F0.08 Drive type selection 
Range:0. 1【0】 
0: Type G (load with constant torque) 
1: Type P (fan & pump load) 
EV2000 series drive of 45kW or below uses the type G 
and type P integrated mode. The power of motor 
matched with the drive type G is lower than that of type 
P. Please refer to Table 2-2 for details. 
The factory setting of the drive is set to type G.   
For example: EV2000-4T0055G/0075P drive’s factory 
setting is 5.5kW type G drive. If the drive needs to be 
changed to 7.5kW type P drive, then: 
①set this parameter to 1 
②set group FH parameters again 
 Note: 
Follow the same procedures if the drive needs to be 
changed from type P to type G. 
F0.09 Torque boost 
Range:0~30.0%【0.0%】 
In order to compensate the torque drop at low frequency, 
the drive can boost the voltage so as to boost the torque. 
If F0.09 is set to 0, auto torque boost is enabled and if 
F0.09 is set non-zero, manual torque boost is enabled, 
as shown in Fig. 5-3.

value) 
 Note: 
1. Wrong parameter setting can cause overheat or 
over-current protection of the motor. 
2. Refer to F0.21 for definition of fz. 
3. When the drive drives a synchronous motor,torque boost 
function is recommended to be used and V/F curve should 
be adjusted according to the motor parameters.
