Description
0: Active high
If the AI terminal is a high level terminal, this terminal is active when the value of
the corresponding bit of A1‑10 is set to 0 and inactive when set to 1.
0: Active low
If the AI terminal is a low level terminal, this terminal is inactive when the value of
the corresponding bit of A1‑10 is set to 0 and active when set to 1.
2.19 A5 Control Optimization Parameters
A5-00
DPWM switchover frequency upper limit
Address:
0xA500
Min.:
0
Unit:
Hz
Max.: F0‑10 Data type: UInt16
Default:
12
Change: In real time
Value Range:
0.00 Hz to value of F0‑10
Description
The AC drive has two PWM modes, including CPWM and DPWM. When the running
frequency is higher than A5‑00 (Switchover frequency), the DPWM mode is used.
When the running frequency is lower than A5‑00 (Switchover frequency), the
CPWM mode is used. The DPWM mode is used to improve the AC drive efficiency,
and the CPWM mode is used to reduce the motor noise.
Increasing A5‑00 to the maximum frequency will reduce the motor noise.
