NOTE:
1. In order to obtain a better control characteristic, carrier frequency and the maximum
operation frequency of AC drive ratio less than 36 is not recommended.
2. The current display value will has deviation when the carrier freq
uency value is too
low.

Carrier frequency
adjustment with
temperature
Setting Range：0～1 0
0：Not adjust, 1：Adjust
It is used to set whether the carrier frequency is adjusted based on the temperature. The AC
drive automatically reduces the carrier fre
quency when detecting that the
heatsink temperature is high. The AC drive resumes the carrier
frequency to the set value when the heatsink temperature
becomes normal. This function reduces the overheat alarms.
P0.12
Acceleration time 1
Setting Range：0.1～6000.0 20.0
P0.13
Deceleration time 1
Setting Range：0.1～6000.0 20.0
Acceleration time indicates the time required by the AC drive to accelerate from 0 Hz to
"Acceleration/Deceleration base frequency" (P0.05), that is, t1 in Figure 6-1.
Deceleration time indicates the time required by the AC drive to decelerate from
"Acceleration/Deceleration base frequency" (P0.05) to 0 Hz, that is, t2 in Figure 6-1.
The DGI900 provides totally four groups of acceleration/deceleration time for selection. You
