IDNP3023 (35 791) 2nd Filter Time Constant Velocity Control
With ARLP2 a second filter can be adjusted in the velocity control loop. This filter is a sim-
ple low-pass filter of first order. With ARLP2 the frequency of the low-pass filter is defined.
With default setting of ARLP2 = 0 this second filter is switched off.
