Analog Inputs

The analog inputs are single ended inputs with the following

characteristics:

Maximum Input Voltage Range: ±10V DC

A/D Converters Two converters selectable via software controlled

analog switches. Standard converter for spindle and

positioning applications and optional converter for

continuous path contouring applications and torque

mode operation.

A/D Resolution-Standard Converter

Effective 14 bits over ±10V DC or 1.22 mV = 1 LSB.

Within –0.039 < x < +0.039 range, 0.076 mV = 1 LSB

Sample Rate

Small Input Change: 0.8 ms

Large Input Change: ≤ 26.4 ms

A/D Resolution-Optional Converter:

True 14 bits over ±10V DC or 1.22 mV = 1 LSB

Sample Rate: 0.8 ms

Noise Filtering: Baluns, Capacitors, and Clamp Diodes

The drive continuously samples to determine long term zero reference drift

of the analog circuitry within the drive and compensates for this drift.

Analog Outputs

The two analog outputs are single ended outputs suitable for driving

voltmeter displays or providing input signals to other electronic control

devices. The outputs have the following characteristics:

Output Voltage: ±10V DC

D/A Resolution: 12 bits over ±10V DC or 11 bits over 0-10V DC

4.88 mV = 1 LSB

Output Update Interval: 1.6 ms

Output Current: 1 mA typical, short circuit protected

Output Impedance: 440 Ohms

Noise Filtering: Baluns and Capacitors

Output: Output capable of driving normal loads such as meters

and analog input circuits through normal shielded or

unshielded cables.

The outputs can be configured through programming to provide either

unipolar or bipolar outputs. The unipolar output represents the absolute

value of the variable while the bipolar output represents both magnitude

and direction of the variable.

Serial Port

The Serial Port can be jumper configured for RS-422 or RS-232 serial

communications with a baud rate of 9,600 baud.
