1.3 AC Drive Application Precautions
1.3.1 AC Drive Selection
1.3.1.1 Drive Capacity
Before driving motors, ensure the motor rated current is lower than the drive rated output. In
addition, when a single AC drive is driving more than 1 motor in parallel, make sure the drive
capacity is higher than 110% of total motor rated current.
1.3.1.2 Starting Torque
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.
