ELECTRICAL INSTALLATION
26 ACR7000 Controller Installation Guide
Axis Connector Power Source
Each Axis (and Auxiliary Encoder) connector has a n5 VDC power source to aid application installations.
The power source typically is used to power:
•
An external encoder
•
Optical inputs and/or outputs between the ACR7000 and an external drive
Description Min Max Units
Continuous current, +5V -- 150
1
mA
Trip current, +5V 700 1200 mA
Voltage tolerance from +5V (@ 150 mA or less) 4.9 5.5 VDC
1. Maximum current draw per Axis/Encoder Connector is 250 mA, not to exceed a combined
1500 mA for eight axis connectors and two auxiliary encoder connectors.
Note: All parameters are at the connector pin.
Equivalent Circuit for Axis Power Source
Axis Connector Fuse
The Axis connector has a +5V voltage source for powering an encoder and/or drive I/O, and includes a fuse, as
shown in Figure 8 above. In the event the +5V source shorts to ground, the internal reset-able fuse disables the
+5V source. When the short-circuit condition is removed and the fuse cools, the fuse automatically resets.
