Electrical Specifications
Digital Power Supply
The +5V and ground reference lines from the power supply should be connected to TB1 terminal block of
the Power PMAC Clipper board using 18 AWG stranded wire. The power requirement (± 5%) is:
+5 V (20W) @ 3.5 A (Four-channel configuration with a typical load of encoders)
+5 V (20W) @ 5.5 A (Eight-channel ACC-24S3 configuration with a typical load of encoders)
Note
Clipper base board requires 2.75A with no other connections. Size
your application accordingly to your encoder load. The above assumes
typical encoder loads at ~100mA per encoder.
DAC Outputs Power Supply
The ±12V lines from the supply, including the ground reference, can be brought in from the TB1 terminal
block.
+12 to +15 V (4.5W) @ 0.30 A (Four-channel configuration with a typical DAC load)
-12 to -15 V (3.8W) @ 0.25 A
+12 to +15 V (4.5W) @ 0.50 A (Eight-channel configuration with a typical DAC load)
-12 to -15 V (3.8W) @ 0.45 A
Flags Power Supply
Each channel of PMAC has five dedicated digital inputs on the machine connector: PLIMn, MLIMn
(overtravel limits), HOMEn (home flag), FAULTn (amplifier fault), and USERn. A power supply from 5
to 24V must be used to power the circuits related to these inputs. This power supply can be the same
used to Power PMAC Clipper and can be connected from the TB1 terminal block.
