Cable Installation
All connectors are on the front panel of the ACR90x0 controller. You may
install cables in any order; however, make sure to install the power cord
last
.
For convenience, we recommend starting with the connections at the bottom
of the front panel. Refer to Chapter 2 Specifications for connector locations,
specifications, and pinouts.
As with any D-sub connector, make sure the securing screws are sufficiently
tightened to secure the cable connection to the controller.
Cable Routing
Route the high power cable (AC mains) at a right angle to low power cables
(communications and inputs/outputs).
Never route high and low power
cables parallel to each other.
Cable EMC Requirements
EMC Ready Cables
Many Parker Hannifin cables are EMC installation ready. If installed
according to the instructions in

, these cables aid the user in gaining
European Compliance, and therefore are an integral part of a CE-system
solution. EMC cables add RF screening and bonding to reduce emissions,
increase immunity, and provide high-integrity safety-Earth bonding. They
also help to reduce problems in environments with high electrical noise.
Non-EMC Cables
Parker Hannifin also offers non-EMC cables, for applications in which CE
compliance is not required or ambient electrical noise does not cause
problems. Because these cables are either unshielded, or contain simple-foil
shielding terminated by a drain wire, they do not provide significant shielding
of electrical noise at high frequencies.
Enable Connection
The ACR90x0 provides one user-enabled interface for emergency stop
purposes. The Motion Enable connector (labeled “E
NABLE
” on the front of the
unit) is a two-pin removable screw terminal located on the front panel of the
unit. The Anode (+) and Cathode (
−
) are on separate connector pins to allow
flexibility in wiring to different styles of interface. A current must flow through
the Motion Enable input for motion to occur on any axis.
Warning —
Damage to the ACR90x0 will result if the 24 Volt supply used on
the Motion Enable input is shared with an inductive load (such as brakes,
solenoids, contactors, or relays).
Do not use the same power supply as your inductive loads unless you place
a loop-back diode as shown in Figure 27. (Place the diode as close as
possible to the inductive load to reduce the possibility of emitted electrical
noise.)
