3300A Spindle Motor SmartDriver Board
To be used only with the 3300A-8 Test System.
For stand-alone driver, see 3400A.
Features:
- Easy to Use:
- Setup through a simple PC program
- Operate the motor through PC program or use stand-alone
- Speed control: High-resolution for accuracy and precision with or without load (.02%-.08% depending on motor speed and number of poles)
- Low Jitter: Typically <1uS
- Motor speed: Maximum 30K RPM
- Programmable motor power supply
- 0-24V, 0-4A output
- Better than +/-1% Voltage Output Adjustment Accuracy
- Over-current and lock rotor protection: Virtually eliminates motor or driver damage
- Unique design:
- All-digital design. No pots to adjust.
- Unidirectional motor quick start: No reverse motor rotation
- Constant current ramp for short start time and motor protection
- 200 kHz PWM current regulator for better speed control and efficiency
- Communication with driver through RS232 port allows:
- Motor Configuration for Speed; Motor poles; Max drive current; Over-current limit: start and run; Time limit expired: start, ramp, lock
- Motor Control Commands for Run; Coast; Brake; Stop; Clear errors; Reset
- Data Query for Run current; Speed; State: off, starting, ramping locking, locked, active brake, coasting, braking; Over-current limit error: start, run; Time limit expired error: start, ramp, lock
- Easy integration into your test environment:
- Communicate through a standard RS232 (USB adaptor available)
- LabVIEW Library and example code
- Windows DLL
- Digital I/O motor control:
- Input for controlling run/stop
- Output to indicate speed lock/error
- Instrumentation interface signals:
- Current sense resistor: direct differential connection
- Run-current voltage: amplified to 1Amp/Volt Scale with analog ground
- Once-per-rev index digital output
