Meters
The Meter Options are Output Voltmeter, Output Speed Meter, and Output
Ammeter. A total of four analog meters can be installed in the ACS 502.
Output Voltmeter
The Output Voltmeter indicates motor voltage on a 0 – 500 VAC scale
connected directly to the drive output.
Output Speed Meter The Output Speed Meter is calibrated in percent of maximum speed with a
0 – 100 percent scale connected to one of the analog outputs.
Note: This option uses one of the analog outputs on the ACS 502.
Output Ammeters The Ammeters have six calibration sizes ranging from 100 to 500 amps.
Depending on the number of motors driven, one or two Output Ammeters can
be installed in the ACS 502. If two ammeters are ordered, two Thermal Motor
Overload Relays must be ordered; the ammeters are sized to the Thermal
Motor Overload Relays. If two Thermal Motor Overload Relays are ordered
and only one ammeter is ordered, the ammeter will indicate the sum of the
current at the two relays.
