Short Description Max. velocity


The VLIMN parameter defines the maximum velocity for the negative direction (velocity control loop) in units defined by VUNIT.
VLIM is also used for limiting the following parameters:
1. MVANGLB <= 0.9*VLIM
3. PVMAX <= (VLIM * PGEARI * 2^PRBASE) / (60 * PGEARO)

When used together with the VLIMN parameter, it is possible to implement a directionally-dependent rotational velocity limit. The VLIM command determines the maximum velocity for both positive and negative directions. By making a subsequent entry for VLIMN, the limit for the negative direction can be set separately.
