DMC1500 Datasheet, PDF (21/67 Pages) List of Unclassifed Manufacturers – versatile digital motor controller

Spectrum Digital, Inc
2.4.3 P5-P6, Phase W Hookup
Connectors P5 and P6 are for the Phase W+ and W- signals respectively. These are
tab terminals. These lines should be connected directly to your motor. For BLDC and
ACI motors connect Phase W to P1. For SR motors connect Phase W between P1 and
P2. Make sure JP3 is cut or open for SR motors.
2.4.4 P7, Ground
Connector P7 is for motor ground. These is a male Tab terminal. This line should be
connected directly to your motor.
2.4.5 P8, Phase U External Driver Power
The high side driver in U2 is normally powered by the boot strap method. If you
want to have continuous gate drive voltage then you can apply 12-15VDC to
connectors P8. This voltage supply must be isolated from P9, P10, and from ground.
Separate isolated supplies must be used for each driver.
2.4.6 P9, Phase V External Driver Power
The high side driver in U3 is normally powered by the boot strap method. If you
want to have continuous gate drive voltage then you can apply 12-15VDC to
connectors P9. This voltage supply must be isolated from P8, P10, and from ground.
Separate isolated supplies must be used for each driver.
2.4.7 P10, Phase W External Driver Power
The high side driver in U4 is normally powered by the boot strap method. If you
want to have continuous gate drive voltage then you can apply 12-15VDC to
connectors P10. This voltage supply must be isolated from P8, P9, and from ground.
Separate isolated supplies must be used for each driver.
2.4.8 P11-P12, PFC Inductor Terminals
These terminals are not used in standard configurations.
2.4.9 P13, Frame Ground
The terminal should be connected to Earth ground.
2.4.10 P14, Motor Center Tap Connection
The terminal is used for the center tap connection for PSC motors.
