Description: Sets the ramp-up/ramp-down time for the rotating measurement.
The following applies for negative values:
When the function module "extended setpoint channel" is activated (r0108.8 = 1), the maximum of the ramp-
up/ramp-down time of the setpoint channel becomes effective. When this function module is inactive, then no ramp-
up/ramp-down time is effective.
The following applies for positive values:
The selected ramp-up/ramp-down time becomes effective.
Recommend.: A ramp-up/ramp-down time should not be activated for the motor data identification (p1958 = 0) as long as this can
be safely done without incurring any danger. This means that the identification is complete and more accurate.
When the ramp-up/ramp-down time is activated, the following steps of the rotating motor data identification are not
executed:
- p1959.5 (identifying the q inductance)
- p1959.7 (identifying the reluctance torque constant)
Dependency: Refer to: p1959, p1960

Description: Sets the configuration of the rotating measurement.
Recommend.: A direction inhibit should not be activated for the rotating measurement (p1959.14 = 1 and p1959.15 = 1) as long as
this can be done without incurring any danger. This means that the identification is complete and more accurate.
When the direction inhibit is activated, the reluctance torque constant (p1959.7) is not identified and the angular
commutation offset (p1959.10, p0431) is inaccurately determined. The reluctance torque constant (p1959.7) is also
not identified in encoderless operation.
Bit field: Bit Signal name
00 Reserved
01 Identify the saturation characteristic
02 Identify the moment of inertia
05 Identify the q inductance
06 Identify the torque constant
07 Identify the reluctance torque constant
08 Identify the q inductance at the test stand
09 Identify the magnetizing current / magnetiz-
ing inductance
10 Identify the commutation angle and direc-
tion of rotation
11 Identify rotor resistance
14 Positive direction permitted
15 Negative direction permitted
Dependency: Refer to: p1958, p1960
Notice: The step p1959.8 (identify q inductance on the test stand) may only be selected if the drive can be kept at zero
speed or at a fixed speed either using a test stand or other mechanical measures.
During steps p1959.2 (identifying the moment of inertia) and p1959.6 (identifying the torque constant) the Vdc_min
controller is disabled (p1240).
