9.1.13 TR Grey – Velocity Integration Time
The Attribute specifies the integration time in [ms] for the parameter TR Grey – Velocity
Format, see Page 62.
The parameter serves to calculate the velocity, which is output via the cyclic process data. The
velocity is specified in [ (steps/integration time) * factor ]. Long integration times allow high-resolution
measurements at low speeds. Low integration times show velocity changes more quickly and are
suitable for high velocities and high dynamics.

Example
Given:
- Programmed resolution = 8192 steps per revolution
- Speed = 4800 revolutions per minute
- Integration time t
i
= 50 ms = 0.05 s
- Factor = 1
Determine:
- Output value in (steps/integration time) * factor
Number of steps / s =
8192 steps * 4800 rev.
=
655360 steps
Rev. * 60 s
1 s
Number of steps/t =
655360 steps
* 0.05 s = 32768 steps
1 s
(Steps/integration time) * factor = 32768 steps / 50 ms

Use the setting Channel coupled = on
to specify whether the
non-safety-related channel TR Grey should be linked to the safety-
related TR Safety
channel. The position and velocity settings are
used by the safety-related channel TR Safety
and the current
settings in the channel TR Grey are ignored.
The preset function can only be performed in the safety-related
TR Safety
channel, but the preset function in the
non-safety-related
TR Grey
channel is disabled.
