How to Bench Test an ATV600/ATV900 Drive Using an Undersized Motor
Resolution
Important: The following configuration is intended for temporary bench testing and functional verification only. It must not be used as a permanent installation, as improper motor protection and motor damage may occur.
Configure the drive as follows:
1. Change the Motor Control Law
Set:
- CTT = UF5Pt
It is not necessary to configure the five voltage/frequency points.
2. Enter Motor Nameplate Data
Set:
- MPC (cos φ) = Motor nameplate power factor
- FRS = Motor rated frequency (Hz)
- UNS = Motor rated voltage
Note: Enter the motor's rated voltage, not the incoming supply voltage.
3. Do Not Run an Autotune
- Do NOT perform an autotune while using an undersized motor.
4. Limit Motor Current
Reduce the current limit:
- CLI = Motor full-load current (FLA), or the closest available setting
5. Disable Motor Compensation Functions
Set the following parameters:
- UFR (IR Compensation) = 0
- SLP (Slip Compensation) = 0
- SPGU (Inertia Factor) = 0
- BOA (Boost) = Inactive
