1.3.1.1 Direct
drives
The feedback module F12 supports the following feedback systems:
!
Distance coding with 1VSS - Interface
!
Distance coding with RS422 - Interface (Encoder)
1.3.1.2
Switching frequency of the power output stage can be set
The
switching frequency of the power output stage
(see on page 38) can be
increased if necessary. This helps mainly to reduce motor sounds.
Please note that power output stage losses increase with rising switching
frequency. Therefore the nominal device currents must be reduced.
1.3.1.3
Predefined external setpoint value optimized via analogue input
Given an external discrete signal read in via the analog input (possible with I10 T10
and T40), signal steps can only be avoided by averaging.
1.3.1.4 UL
certification
Compax3 now with
UL certification.
