JSP-090-10

JSP-090-10 is a Copley Controls unit in the Junus Motor Controllers series. It operates with a bus voltage from 20 VDC to a maximum of 90 VDC, establishing the supported DC supply range. The controller provides 5 ADC of continuous current and 10 ADC of peak current for up to 1 second. Continuous output power is 0.43 kW, while peak output power is 0.85 kW for short-duration load demands. Its overtemperature threshold is 70ºC, at which thermal protection is activated.

The analog input has 12-bit resolution for converting command signals into digital values, and its 66 kΩ input impedance limits loading on the connected signal source. The digital output can sink 1 ADC for controlling a compatible external load. The current loop updates at 20 kHz for current regulation, while the velocity loop updates at 4 kHz for speed control. A 20 kHz PWM carrier controls power switching, and the 220 ns minimum PWM pulse width establishes the shortest switching command the controller can produce. The PWM ripple frequency is 40 kHz, indicating the frequency of current ripple associated with PWM operation.
