p1470[0...n] Speed controller encoderless operation P-gain / n_ctrl SL Kp
Access level: 2 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6040, 6050
Min:
0.000
Max:
999999.000
Factory setting:
0.300
Description: Sets the P gain for encoderless operation for the speed controller.
Note
The product p0341 x p0342 is taken into account when automatically calculating the speed controller (p0340 = 1, 3, 4).
p1472[0...n] Speed controller encoderless operation integral time / n_ctrl SL Tn
Access level: 2 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6040, 6050
Min:
0.0 [ms]
Max:

Factory setting:
20.0 [ms]
Description: Set the integral time for encoderless operation for the speed controller.
Note
The integral component is stopped if the complete controller output or the sum of controller output and torque precontrol
reach the torque limit.

Description: Display and connector output for the torque setpoint at the output of the I speed controller.
r1493 CO: Moment of inertia total, scaled / M_inert tot scal
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: 25_1 Unit selection: p0100 Function diagram: 6031
Min:
- [kgm²]
Max:
- [kgm²]
Factory setting:
- [kgm²]
Description: Display and connector output for the parameterized total moment of inertia.
The value is calculated as follows: (p0341 * p0342) + p1496
p1496[0...n] Acceleration precontrol scaling / a_prectrl scal
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6020, 6031
Min:
0.0 [%]
Max:
10000.0 [%]
Factory setting:
0.0 [%]
Description: Sets the scaling for the acceleration precontrol of the speed/velocity controller.
