The motor characteristics at start and during acceleration are limited by the drive overcurrent. 
If higher starting torque is needed, use a higher rating drive or increase capacity of both motor 
and drive. 
1.3.1.3 Emergency Stop 
When a drive fault occurs, protection function will be automatically triggered to shut off the 
output but the motor may not stop immediately. Therefore please install mechanical brake if 
immediate stop is necessary.   
1.3.2 Settings 
1.3.2.1 Upper Limits 
The maximum output frequency of the drive is 400Hz. If the upper limit is set incorrectly, the 
motor will run at higher than its rated speed and cause danger. Please set the limit of output 
frequency in Frequency Upper Limit parameter. The default setting of the rated output 
frequency is 60Hz. 
1.3.2.2 DC Braking 
Excessive DC braking current and duration could cause motor overheat. 
1.3.2.3 Acceleration /Deceleration Time (Acc./Dec. Time) 
Acceleration and deceleration time is determined by the motor torque, load torque and load 
inertia. Set a longer Acc./Dec. time after Stall Prevention function is triggered. In addition, the 
acceleration and deceleration time will be extended depending on the Stall Prevention 
duration. If faster acceleration and deceleration are required, install proper braking options or 
use a higher rating motor and AC drive.   
1.3.3 General Handling 
1.3.3.1 Wiring 
Connecting power supply to output terminals U/T1, V/T2 and W/T3 will damage the drive. 
Check all the connections and wiring sequence before turning on the power. Failure to comply 
could cause drive damage.
