Operation of command invalidation (forced zero) differs between the position and
velocity control types. For the position control type, command pulses are inhibited, and
for the velocity control type, the velocity command becomes zero (VCMD = 0).
These settings are validated when the acceleration/deceleration time (Tvac, Tvde) or
low pass filter (VLPF) parameter is set.

Sequence current limit value can be changed by SILM in the Parameter Mode 1 on
