Operating Specifications
The drive controller and motor are designed to operate under the following conditions and with the following performance characteristics:

1. Voltage: 230V + 10%, -5%; single phase; 60 Hz
2. Maximum Operating Ambient Temperature: 40°C (104 F). 
3. Speed Deviation (Regulation): Under conditions of constant line voltage and constant temperature, the total speed deviation of the motor with a load change from 10% of full load to 100% will not exceed 1% of the rated motor base speed with tachometer feedback and 2% with armature feedback. This speed regulation will be obtained at any speed between base speed and 1/30 of base speed. For example, a motor having a base speed of 1750 RPM will not experience a speed deviation of more than 17.5 RPM under this load change with tachometer feedback and 35 RPM with armature feedback . The speed deviation is affected by ambient temperature and line voltage changes. A change in ambient temperature from 25°C to 40°C could produce a speed change as great as 6% if the line voltage is held constant. Similarly, a variation in line voltage of 10% could produce a speed change of 6% if the temperature is held constant.
4. Maximum Permissible Continuous Torque: The actual load that can be drawn from the motor or the duty cycle which it can sustain depends on the motor frame and enclosure. If a motor is to be operated at greatly reduced speed for long periods of time, it may be necessary to derate the motor in accordance with the table below.
