Note: The closed-loop torque control can only be changed over in operation (p1300 = 20, 21) by selecting the closed-loop
speed control (p1501). At the changeover, the setting of p1300 does not change. In this case, the actual state is dis-
played in r1407, bit 2 and bit 3.
For encoderless operation (p1404 = 0 or p1300 = 20), the following applies:
- The following condition must be fulfilled: p1800 >= n / (2 * p0115[0]), n = 1, 2, ...
- For motors with a small power rating (< 300 W) we recommend to set n >= 2.

SERVO_S110-DP,
Data type: Integer16
SERVO_S110-PN
P-Group: -

Description: Setting to activate the U/f control with linear characteristic.
Value: 0:
1:
Dependency: Refer to: p1318, p1319, p1326, p1327
Note: The following applies for firmware version 4.3 and higher:
When U/f control is activated, resonance damping is automatically activated. The resonance damping must be de-
activated (p1338 = 0) in order to obtain pure diagnostics operation without the influence of actual values.
Further, when U/f control is activated, the following functions are active:
- Vdc controller (p1240, p1244, p1248, p1250).
- the up ramp is limited by the set M, P and I limits (p0326, p0341, p0342, p0640, p1520, p1521, p1530, p1531,
p1498).
- the ramp-function generator is held if the current actual value exceeds the current limit set in p0640.
p1318[0...n] U/f control ramp-up/ramp-down time / Uf t_rmp-up_rmp-dn
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
0.000 [s]
Description: Sets the ramp-up and ramp-down time for the U/f control.
The ramp-function generator requires this time to reach the maximum speed (p1082) from zero.
Dependency: Refer to: p1317, p1319, p1326, p1327
Note: This ramp is used for stall protection and operates independently of any ramp-function generator that might have
been configured.
p1319[0...n] U/f control voltage at zero frequency / Uf U at f=0 Hz
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: V/f open-loop control
Not for motor type: -
Min
0.0 [Vrms]
Description: The linear characteristic for the U/f control is defined by 0 Hz / p1319 and p1326 / p1327.
This parameter specifies the voltage for a frequency of 0 Hz.
Dependency: The U/f control is activated via p1317 = 1.
Refer to: p1317, p1326, p1327
Note: Linear interpolation is carried out between the points 0 Hz/p1319 and p1326/p1327.
