General information

Digital drive systems and position control loops require fast and highly secure transfer of data obtained from position measuring instruments. In addition, other data such as drive-specific characteristic values, correction tables, etc. should also be available. To ensure a high level of system security, measuring instruments must be integrated in routines for detecting errors and be able to perform diagnostics.

The EnDat interface from HEIDENHAIN is a digital, bidirectional interface for measuring instruments. It is able to output position values from incremental and absolute measuring instruments and can also read and update information on the measuring instrument or store new data there. Because it relies on serial data transfer, only 4 signal lines are needed. The data is transferred synchronous to the clock signal defined by the subsequent electronics. The transfer method (position values, parameters, diagnostics, etc.) is selected with mode commands that the subsequent electronics transmit to the measuring instrument.

Holding brake

The holding brake is a permanent magnet brake. Voltage (see the technical data) must be applied to release the brake. Based on principle, this type of holding brake exhibits a minimal amount of backlash.

The brake is designed as a holding brake. It not permitted to be used for operational braking! Loaded braking during an emergency stop is permitted but reduces its service life.

The required brake holding torque is determined based on the actual load torque. It is recommended by the brake manufacturer to take into account a safety factor of 2.

The holding brake is not intended for normal braking. The maximum motor torque far exceeds the holding torque for the brake.

The number of revolutions of the motor shaft with the holding brake applied is not permitted to exceed the value 3200 since safety function STO can no longer be ensured in this case. The current value of the revolutions when the holding brake is applied can be read out under parameter ID BRAKE_WEARMON_REVO.Values are only valid for size 2.

The brake is designed as a holding brake. It not permitted to be used for operational braking! Loaded braking during an emergency stop is permitted but reduces its service life.

8D1A - Shaft end design

ACOPOSmotor Compact modules (8D1A) can be delivered with a smooth shaft end or keyed shaft end.

A smooth shaft end is used for a force-fit shaft-hub connection and guarantees a backlash-free connection between the shaft and hub as well as a high degree of operating smoothness. The end of the shaft has a threaded center hole.

A keyed shaft end is used for a form-fit torque transfer with low demands on the shaft-hub connection and for handling torque in a constant direction.
The keyways for ACOPOSmotor Compact modules conform to keyway form N1 per DIN 6885-1. Form A keyed shafts that conform to DIN 6885-1 are used. Balancing motors with keyways is done using the shaft and fitment key convention per DIN ISO 8821.
The end of the shaft has a threaded center hole that can be used to install machine actuators with shaft end cover plates.

8D1A - Oil seal

All ACOPOSmotor Compact modules without gearbox (8D1A) are available with an optional form A oil seal per DIN 3760.
With an oil seal, the ACOPOSmotor Compact modules meet the requirements for IP65 protection per EN 60529.
Proper lubrication of the oil seal must be ensured throughout the entire service life of the motor.
