Planning and installation
1. Features
The 9200 controller series comprises 3 supply modules (types
9212, 9215 and 9217) and 7 servo modules (types 9222-9228 with
motor peak currents ranging from 8 to 82 A) for asynchronous
servo motors.
•
Digital control by 16-bit microcontroller and 3 ASICs
•
Field-orientated vector controlled current
•
Four-quadrant operation, any speed and torque direction
