Setpoint channel and closed-loop control
7.4 Vector speed/torque control with/without encoder
Supplementary conditions
● Maximum speed or maximum torque depend on the converter output voltage available
● Calculating the maximum speed:
● Depending on the terminal voltage and load cycle, the maximum torque can be taken
● No thermal model is available for the closed-loop control of a permanent-magnet
Commissioning
The following sequence is recommended for commissioning:
● Configure the drive
● Motor identification (standstill measurement, p1910)
● Speed controller optimization (rotary measurement, p1960)

synchronous motor. The motor can only be protected against overheating by using
temperature sensors (PTC, KTY). To achieve a high level of torque accuracy, we
recommend the use of a temperature sensor (KTY) to measure the motor temperature.
When the drive is being commissioned using STARTER or the AOP30 operator panel,
the permanent-magnet synchronous motor must be selected. The motor data specified in
the table below must then be entered. Finally, the motor identification routine and speed
optimization (p1900) are activated. Encoder adjustment is activated automatically
together with the motor identification routine.
Comment
If this value is not known, the value "0" can also be
entered.
Entering the correct value, however, means that the
stator leakage inductance (p0356, p0357) can be
calculated more accurately.
If this value is not known, the value "0" can also be
entered.
If this value is not known, the value "0" can also be
entered.
