Parameters
11.2 Parameter list
Par. No. Name
p2000 Reference speed
Description: Sets the reference quantity for speed and frequency.
All speeds or frequencies specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 40000000 hex (double word).
Dependency: Refer to: p2003
p2002 Reference current
Description: Sets the reference quantity for currents.
All currents specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
Notice: If various DDS are used with different motor data, then the reference quantities remain the same as
these are not changed over with the DDS. The resulting conversion factor should be taken into account (e.g.
for trace records).
Example:
p2002 = 100 A
Reference quantity 100 A corresponds to 100 %
p2003 Reference torque
Description: Sets the referene quantity for torque.
All torques specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 40000000 hex (double word).
p2153 Speed actual value filter
time constant
Description: Sets the time constant of the PT1 element to smooth the speed/velocity actual value.
The smoothed actual speed/velocity is compared with the threshold values and is only used for messages and
signals.
p2161 * Speed threshold 3
Description: Sets the speed threshold value for the signal that indicates the axis is stationary.
p2162 * Hysteresis speed n_act >
n_max
Description: Sets the hysteresis speed (bandwidth) for the signal "n_act > n_max".
Note:
For a negative speed limit, the hysteresis is effective below the limit value and for a positive speed limit above
the limit value.
If significant overshoot occurs in the maximum speed range (for example, due to load shedding), you are
advised to increase the dynamic response of the speed controller (if possible). If this is insufficient, the hyste-
resis p2162 can be increased, but its value must not be greater than the value calculated by the formula be-
low when the motor maximum speed is sufficiently greater than the maximum speed p1082.
p2162 ≤ 1.05 × motor maximum speed - maximum speed (p1082)
The range of the parameter is different when connect with different motors.
p2175 * Motor blocked speed
threshold
Description: Sets the speed threshold for the message "Motor blocked".
Dependency: Refer to p2177.
