Motor control (MCTRL)
Servo control (SC)
If the mass inertia of the drive is unknown, the optimisation can be achieved as follows:
1. Specify speed setpoint.
2. Increase Vp (C00070/2
) until the drive is unstable (observe motor noise).
3. Reduce Vp (C00070/2
) until the drive runs stable again.
4. Reduce Vp (C00070/2
) to approx. half the value.
Tip!
Values recommended by Lenze for the setting of the (proportional) gain:
• For drive systems without feedback: Vp = 6 … 20
• For drive systems with a good disturbance behaviour: Vp > 12
Speed controller reset time Ti
Apart from setting the P component, C00071/2
provides the possibility to take influence
on the I component of the PI controller.
If the mass inertia of the drive is unknown, the optimisation can be achieved as follows:
1. Specify speed setpoint.
2. Reduce Ti (C00071/2
) until the drive is unstable (observe motor noise).
3. Increase Ti (C00071/2
) until the drive runs stable again.
4. Increase Ti (C00071/2
) to approx. twice the value.
Tip!
Value range recommended by Lenze for the setting of the reset time:
Ti = 20 ms … 150 ms
Differential time constant Tdn (rate time)
The differential time constant Tdn of the speed controller can be set in C00072
.
If the mass inertia of the drive is unknown, the optimisation can be achieved as follows:
Increase Tdn (C00072
) during operation until optimal control mode is reached.
