9.2. Installation and wiring
When installing the PCD2 system particular attention should be paid to
the points listed below. Before powering up the system, a visual check of
the installation and wiring should be made as follows:
•
Has the overall PCD1/2 system suffered any damage during trans-
portation or assembly?
•
Is the H3 module plugged into the space provided on the PCD1/2
bus and is the wiring complete on the relevant bus module?
•
Wiring and connection of user supply:
The H3 module must have a smoothed, +24 V DC supply voltage
(19..32 V, max. ripple 10%) at the "+" and "-" terminals.
•
System earth
For fault-free operation, a perfect earth to divert external noise volt-
age is indispensable. The PCD1/2 system should be connected to the
"GND" terminal (24 VDC -) with the largest possible cross-section
on the earth rail of the control box. It should further be ensured that
all earth lines have been laid without loops.
•
Laying the cables
Regulations prescribe the laying of high-voltage cables and control
cables in separate cable channels.
•
Motor controller output (
±±±±
10V analogue)
Check connections as described in manual, chapter 5.5. The cable
must be shielded.
•
Enable for the driver is triggered through a "normal" digital output of
the PCD1/2.
•
Encoder connections
For special attention with the 5V encoder:
•
Cable must be shielded and lines must be in twisted pairs.
•
Max. cable length 20m, min. conductor cross-section 0.25mm2. In
addition, check that encoder is correctly mounted (no slippage in
coupling), check type and technical data (impulses per revolution).
•
Ref (for PCD2.H310) wire directly
•
LS1 / LS2, for PCD2.H311 also Ref, wire to "normal" digital inputs of
PCD1/2.
