Technical Description
6.4
Options
— Holding brake
— Radial shaft-sealing rings
— Keyway
— EnDat, BISS
With exception of the radial shaft seal the options cannot be retrofitted. Options such as radial shaft
seal, holding brake, EnDat or BISS can lead to a reduction of rated data.

Selection criteria
The three-phase servomotors are designed to operate with AX2000 servo amplifiers. Together, both
units form a closed speed or torque control loop.
The most important selection criteria are:
—
—
—
—
When calculating the motors and servo amplifiers which are required, take account of the static load
and the dynamic load (acceleration/braking). Collected formulae and examples of the calculations
are available from our applications department.

Built-in holding brake.
Motor length increases by the holding brake.
A radial shaft-sealing ring can be supplied at extra charge to seal against oil mist
and oil spray. This increases the protection rating of the shaft bushing to IP67.
The motors are available with keyway and key inserted according to DIN6885
The shaft is balanced with a short (half) key.
Another feedback system is mounted instead of the resolver. The motor length
can increase by the alternative feedback.
