Commissioning
3.14 Commissioning induction motors (ASM)
Features
● Field weakening up to approx. 1.2 * rated speed (this depends on the drive converter
supply voltage and the motor data, also refer to supplementary conditions)
● Flying restart
● Vector closed-loop speed and torque control
● Vector V/f control
● Motor data identification
● Speed controller optimization (rotating measurement)
● Thermal protection via temperature sensor (PTC/KTY/PT1000)
● All encoders that can be connected to an SMC10, SMC20 or SMC30 are supported.
● Operation with or without encoder is possible
Depending on the terminal voltage and load cycle, the maximum torque can be taken from
the motor data sheets / configuration instructions.
Commissioning
To commission induction motors, motor identification and rotating measurement are
recommended. Make the following setting for this:
1. Configure p1900 = 1.
For induction motors, motor data identification (p1910 = 1) and rotating measurement
(p1960) are activated automatically.
- OR -
2. Activate both functions individually:
– Configure the zero speed measurement: p1910 = 1.
– Configure the rotating measurement p1960 = 0,1,2 (depending on p1300).
The optional motor data can be entered if it is known. Otherwise, it is estimated using the
type plate data or is determined using a motor data identification routine or speed controller
optimization.
