Explanatory notes
• The frequency limit for engagement of the holding brake can be set
independently for clockwise and anti-clockwise running.
• The optional monitoring of the motor current (BRK2) provides the
security when the holding brake is opened that the motor is correctly
connected and has already developed torque.
