9.1.3 PP-00851 Converter and protection circuitry for 230 VDC grinding motor
Part Description
1 Input Connection from PP-00581
2 Encoder connection to PP-00581
3 Output Connection to Grinder Motor
The concerning circuitry is specially designed to protect the DC grinding motor(s) against overload
situations.
Additional features are:
• when the motor is blocked the circuitry switches off the motor and send an error code
