The PC800 drives do not require additional filtering in the motor leads as long as the motor power cable (between drive connector TB1 and the motor) is less than 10 meters (32 feet) long. For longer motor power cables, an external balun must be added in series with the cable. Additional information can be found in Pacific Scientific Application Notes 106 (“Reducing Motor Drive Line Noise”) and 107 (“Reducing Motor Drive Radiated Emissions”).

Requirements for Safe Operation of the Drive

 It is the machine builder’s responsibility to insure that the complete machine complies with the Machine Directive (EN60204). The following requirements relate directly to the servo controller: Emergency Stop If personal injury can result from motor motion, the user must provide an external hardwired emergency stop circuit outside the drive. This circuit must simultaneously remove power from the drive’s motor power terminal TB1-11, TB1-12, and TB1-13 and disable the drive (by disconnecting J2 pin 37 from I/O RTN).

The motor will coast under this condition with no braking torque.

 If breaking torque is required to quickly stop the motor, a dynamic brake can be added that loads the motor’s windings resistively. The motor should not be loaded until the servo drive is disabled. Note that the holding brake which is optional on Pacific Scientific motors is not intended to stop a spinning motor. It is designed to prevent a stopped motor from rotating due to an applied torque.
