4.5 Control terminals I/O specification
See Pr 05 on page 38 (Drive configuration) for terminal connection / set-
up diagrams and details.
The digital inputs are positive logic only.
The analogue inputs are unipolar. For information on a bipolar input, see
the Commander SK Advanced User Guide.
0-20: Current input 0 to 20mA (20mA full scale)
20-0: Current input 20 to 0mA (0mA full scale)
4-20: Current input 4 to 20mA with current loop loss (cL1) trip
(20mA full scale)
20-4: Current input 20 to 4mA with current loop loss (cL1) trip
(4mA full scale)
4-.20: Current input 4 to 20mA with no current loop loss (cL1) trip
(20mA full scale)
20-.4: Current input 20 to 4mA with no current loop loss (cL1) trip
(4mA full scale)
VoLt: 0 to 10V input
The total available current from the digital output plus the +24V output is
100mA.
The control circuits are isolated from the power circuits in the
drive by basic insulation (single insulation) only. The installer
must ensure that the external control circuits are insulated from
human contact by at least one layer of insulation (supplementary
insulation) rated for use at the AC supply voltage.
If the control circuits are to be connected to other circuits
classified as Safety Extra Low Voltage (SELV) (e.g. to
personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
The above warnings also apply to the PCB edge connector
for the optional Solutions Modules. To allow a Solutions
Module to be fitted to Commander SK, a protective cover
must be removed to allow access to the PCB edge connector.
See Figure 3-22 on page 27. This protective cover provides
protection from direct contact of the PCB edge connector by
the user. When this cover is removed and a Solutions Module
fitted, the Solutions Module provides the protection from
direct contact by the user. If the Solutions Module is then
removed, this PCB edge connector becomes exposed. The
user is required to provide protection in this case, to protect
against direct contact of this PCB edge connector.
