Description

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
2. MSPEED >= 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.
