44 Chapter 5 Parameter Introductions
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
This function is active in panel control mode and serial
port control mode, and inactive in terminal control mode.

EV2000 Series Universal Variable Speed Drive User Manual
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:
① set this parameter to 1
② set 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
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.

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.
