Digital Inputs; Digital Outputs - Copley Controls Xenus R10 Manual

Accelnet R23
DIGITAl InPuTS
There are ten digital inputs to Accelnet Micro Module, nine of which can be programmed to a selection of functions. The Enable input which controls the
on/off state of the PWM outputs is fixed to [In1] as a safety measure so that a drive cannot be programmed in such a way that, once installed, it could not
be shut down by the controller. Two types of RC filters are used: GP (General-purpose) and HS (High Speed). The input time-constants apply when driven
by active sources (CMOS, TTl, etc). All inputs except [In5] have 10 kW pull-up resistors to +5 Vdc. The pull-up for [In5] is 4.99 k for compatibility with
Copley linear motors. Input functions such as Step/Direction, Countup/CountDown, Quad A/B must be wired to inputs having the HS filters, and inputs with
the GP filters can be used for general purpose logic functions, limit switches, and the motor temperature sensor. In addition to the selection of functions,
the active level for each input is individually programmable.
GP input functions
• Drive enable
• CAn address
• Positive limit switch
• negative limit switch
• Home switch
• Drive Reset
• Motor temperature sensor input
• Motion abort
Drive reset is programmable to take place on transitions of the input and is programmable to 1/0 or 0/1. The motor temp sensor function will disable the
drive if a switch in the motor opens or closes when the motor overheats.

DIGITAl OuTPuTS
Digital outputs [OuT1~3] are open-drain MOSfeTs with 1 kW pull-up resistors in series with a diode
to +5 Vdc. They can sink up to 100 mAdc from external loads operating from power supplies to +30
Vdc. The outputs are typically configured as drive fault and motor brake. Additional functions are
programmable. As a drive fault output, the active level is programmable to be HI or lO when a fault
occurs. As a brake output, it is programmable to be either HI or lO to release a motor brake when the
drive is enabled. When driving inductive loads such as a relay, an external fly-back diode is required.
A diode in the output is for driving PlC inputs that are opto-isolated and connected to +24 Vdc. The
diode prevents conduction from +24 Vdc through the 1 kW resistor to +5 Vdc in the drive. This could
turn the PlC input on, giving a false indication of the drive output state.
+5 VDC OuTPuT
The drive internal +5 Vdc power is made available at P1-28. The output current is 250 mA maximum.
This power should be used with care as there is no linear regulator between the drive internal power
supply and the external circuits as in other Copley drives with +5 Vdc outputs. When using this power
an l-C filter is required. This consists typically of a ferrite-core inductor and an electrolytic capacitor.
A typical value for the capacitor would be 4.7 µf. The inductor can be 50~150 µH and should be rated
for DC current of 250 mA minimum. The capacitor should have a return path to drive power ground
(J1-13,14).
