6.8. Time units
The internal time units are expressed in slow loop sampling periods. The correspondence with the
time in [s] is:
] IU [ Time × T = ] s [ Time
where T – is the slow loop sampling period expressed in [s]. You can read this value in the
“Advanced” dialogue, which can be opened from the “Drive Setup”. For example, if T = 1ms, one
second = 1000 IU.
6.9. Drive temperature units
The drive includes a temperature sensor. The correspondence with the temperature in [
°
C] is:

6.10. Master position units
When the master position is sent via a communication channel or via pulse & direction signals,
the master position units depend on the type of position sensor present on the master axis.
When the master position is an encoder the correspondence with the international standard (SI)
units is:
] IU [ position _ Master ×
lines _ encoder _ No × 4
π × 2
= ] rad [ position _ Master
where:
No_encoder_lines – is the master number of encoder lines per revolution
6.11. Master speed units
The master speed is computed in internal units (IU) as master position units / slow loop sampling
period i.e. the master position variation over one position/speed loop sampling period.
When the master position is an encoder, the correspondence with the international standard (SI)
units is:
] IU [ speed _ Master
T lines _ encoder _ No
] s / rad [ speed _ Master
