CDE500 Vector Control AC Drive Chapter 6 Parameters Description
Group d0: Motor Control
d0.00 ① Range: 0 ~ 2 Default: 0
Motor control
mode
0: V/f
Constant Volt/Hertz proportion control. It is applicable to applications
with low load requirements or applications where one AC drive operates
multiple motors, such as fan and pump.
1: Open loop vector control （ SVC ）
It is applicable to high-performance speed control or torque control
applications without speed encoder. One AC drive can operate only one
motor.
2: Closed loop vector control
（ VC ）
It is applicable to high-accuracy speed control or torque control
applications with speed encoder. One AC drive can operate only one
motor. An encoder and a PG card must be installed and setting correctly
in group L2.
Note:
 If vector control is selected, motor auto-tuning must be performed
before first running. Motor parameters which calculated from
auto-tuning shall be store in Group d1.
 If vector control is selected, the rated power between AC drive and
motor cannot mismatched too much. Otherwise, the performance
could be decreased.
 Motor control mode (d0.00) is used for motor 1, please refer Group
d5 to set for motor 2 when motor 2 is used.
d0.01 Range: 1.0 ~ 16.0 Default: Model dependent
Carrier frequency
Unit: kHz
The default value of carrier frequency is depended on AC drive hardware,
as shown in the table below. It is no need to change this parameter in
common usage. If the set carrier frequency is higher than default
setting, you need to de-rate the AC drive.
If the carrier frequency is low, output current has high harmonics, and the
power loss and temperature rise of the motor increase.
If the carrier frequency is high, power loss and temperature rise of the
motor declines. However, the AC drive has an increase in power loss,
temperature rise and interference.
