SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
0613 Inversion term. 24.x/20.x
Min Standard Max Unit Data type Effective
0 0 1 – Unsigned16 immed.
An inversion inverts the polarity of the analog setpoint at this terminal internally.
1 Inverted
0 Not inverted
0614 Smoothing time, terminal 24.x/20.x
Min Standard Max Unit Data type Effective
0.0 3.0 1000.0 ms Floating Point immed. (ARM)
0.0 0.0 1000.0 ms Floating Point immed. (SRM SLM)
This allows the output value of the A/D converter to be smoothed using a PT1 filter.
0615 Drift/offset correction term. 24.x/20.x
Min Standard Max Unit Data type Effective
–9999.9 0.0 9999.9 mV(pk) Floating Point immed.
If the motor erroneously rotates when a speed setpoint of 0 V is entered, a voltage offset can
be applied to set the analog input to zero using this parameter.
0616:8 Ramp-function generator ramp-up time
Min Standard Max Unit Data type Effective
0.0 2.0 600.0 s Floating Point immed. (ARM)
0.0 0.0 600.0 s Floating Point immed. (SRM SLM)
During ramp-up, the setpoint is increased from zero to the maximum permissible actual speed.
Note:
Max. permissible actual speed for synchronous motors: Minimum from 1.2 x P1400 and P1147
Max. permissible actual speed for induction motors: Minimum from P1146 and P1147
refer to the index entry ”Ramp-function generator”.
From SW 2.4, this parameter is replaced by P1256:8 (P0616:8 = P1256:8).
0617:8 Ramp-function generator ramp-down time
Min Standard Max Unit Data type Effective
0.0 2.0 600.0 s Floating Point immed. (ARM)
0.0 0.0 600.0 s Floating Point immed. (SRM SLM)
During ramp-down, the setpoint is reduced from the maximum permissible actual speed to zero.
Note:
Max. permissible actual speed for synchronous motors: Minimum from 1.2 x P1400 and P1147
Max. permissible actual speed for induction motors: Minimum from P1146 and P1147
refer to the index entry ”Ramp-function generator”.
From SW 2.4 this parameter is replaced by P1257:8 (P0617:8 = P1257:8).
0618 Normalization voltage, speed setpoint
Min Standard Max Unit Data type Effective
5.0 9.0 12.5 V(pk) Floating Point immed.
This defines at which input voltage at terminal 56.x/14.x and/or terminal 24.x/20.x, the maxi-
mum useful motor speed (P1401:8, dependent on the motor data set) is reached for closed-
loop speed controlled operation.
Example:
SRM: P0618 = 9, P1401:8 = 2000 –> at 9 V, the motor speed is 2000 RPM
SLM: P0618 = 9, P1401:8 = 120 –> at 9 V, the motor velocity is 120 m/min
