General notes about the series
Gripping force
when the arithmetic sum of the individual force applied to each jaw at distance P (see illustration) on standstill torque of the motor.
Standstill torque
required standstill torque of the motor to achieve the specified gripping force depending on the motor shaft diameter. This torque must not be exceeded. The required standstill torque for the asynchronous version is halved.
Finger length
is measured from the reference surface as the distance P in direction to the main axis.
Gripping force maintenance
A gripping force of at least 80% of the originally applied gripping force can be reliably maintained in the event of an emergency stop situation or a voltage drop due to an electric holding brake (using motors with motor brake and/or utilizing the position clamping option).
Repeat accuracy (positioning, unidirectional)
defined as the spread of the actual position of the base jaws after 100 consecutive movements to a target position from the same direction under constant conditions.
Closing and opening times
When gripping, the speed must be adapted as described in the operating manual so that the closing and opening times can increase. The times specified are only the movement times of the base jaws at max. speed, max. acceleration without electrical restrictions, and observance of the maximum permissible masses per finger.
