6.2.3.15 Velocity filter type
See also parameter Velocity filter intensity on page 50.
Selection
Value
Description
Default
static
0
The lowpass filter characteristic is applied on the actual
velocity value regardless of the drive’s current motion and
acceleration status, respectively.
X
dynamic
1
The lowpass filter characteristic is deactivated as soon as
the measuring system detects a significant acceleration in
the velocity signal.
The lowpass filter will be reactivated as soon as a uniform
motion is detected from the measuring system.
6.2.3.16 Velocity reference value N2/N4 (PNU 60000)
Alternatively, this parameter can also be set during operation via an acyclic parameter access to the
velocity reference value function PNU 60000, see Page 64.
If the Velocity value normalization parameter is set to N2/N4 normalized (4), the
velocity value output in the NIST_A and NIST_B signals is a percentage of the specified velocity
reference value.
The entry is made in [Rev./min], the default setting is 3000 rev./min = 100%.

Default
3000 rpm
Specifications for the N2/N4 normalization:
 Signal NIST_A corresponds to Scaling N2
 Signal NIST_B corresponds to Scaling N4
 0 % = 0x0
 N2: 100% of the velocity reference value = 0x4000 (2
14
), resolution: 2
–14
* 100%
 N4: 100% of the velocity reference value = 0x4000 0000 (2
30
), resolution: 2
-30
* 100%
 Value range: -200% up to +200%
 MSB = 1: negative sign
 MSB = 0: positive sign
