Epsilon Eb Digital Servo Drive Installation Manual

	Epsilon Series
	Differential line driver, RS-422 and TTL compatible
	Scalable in one line increment resolution up to 2048 lines/rev of the motor (MG and NT)
	Output Device = AM26C31
Encoder Output Signal	20 mA per channel, sink and/or source
	Vout Hi @ 20 mA = 3.8 - 4.5 V
	Vout Lo @ 20 mA = 0.2 - 0.4 V
	Vout diff w/100 ohm termination = 2.0 - 3.1 V
	Vout common mode w/100 ohm termination = 0.0 - 3.0 V
	Iout short circuit = 30 - 130 mA
	Internal: At full speed, use full torque decel and 5:1 inertial load for Eb 202/203 with NT-
	212 or Eb-205 with MG-340. Repetition frequency limited only by drive RMS capacity. No
Shunt Resistor Capacity/	internal shunt resistor.

Cooling Method	Eb-202, Eb-203, Eb-205: Convection
	Ambient temperature range for rated output: 32° F to 104° F (O° C to 40° C)
	Maximum ambient operating temperature: 104° F to 122° F (40° C to 50° C) with power
	derating of 3%/°C
Environmental	Rated altitude: 3,280 feet (1000 m)
	Vibration: 10 - 2000 Hz at 2g
	Humidity requirement: 10 - 95% non-condensing
	Storage temperature: -13 °F to 167 °F (-25 °C to 75 °C)
	Temperature:
	Operation in ambient temperature over 50° C (122° F) not recommended.
Derating	Drive output power must be derated by 3 %/°C between 104° F to 122° F (40° C to 50° C)
	Derating altitude: Above 3,280.8 ft (1000 m) reduce output by 1% per 328.08 ft (100 m)
