DNTS2, 3, 4, 5
Speed, Distance, and Delta just as with DNTS-1 but with distances and
speeds per your Contract Speed. For any switch that has been set to “unused”, parameters can
all be set to 0.0.
• For reduced stroke buffers, refer to UNTS2, 3, 4, 5 on page 4-131 .
Brake Pick Delay, 133
The time in milliseconds after the drive enable command is
issued and acknowledged before the brake should pick. The default time of 0 (zero) millisec-
onds should be appropriate for virtually all scenarios.
Speed Pick Delay, 134
The time in milliseconds after the brake is picked before the
speed command is issued. This setting is used to prevent beginning movement under a slow-
picking brake. The default of 500 milliseconds is a good starting point.

Brake Hold Delay, 135
After take off, the brake is held fully picked until this timer
expires, at which point it settles to hold position/voltage. Default time for a geared machine is
2000 ms. Default time for a gearless machine is 800 ms.
