3.2 Function description
The servo motor is controlled by a servo drive according to a programmable motion profile and rotates,
accelerates or decelerates the output flange (rotary plate) of the product.
The output flange (rotary plate) can rotate left, right or alternatingly.
The integrated encoder provides for high positioning accuracy and repeatability.
The optional holding brake holds the output flange (rotary plate) in position when it is at a standstill.
The braking force is generated by means of springs. The holding brake is released when voltage is
applied; the holding brake is applied when the supply voltage is switched off or in the case of power
outages.
Product type ST0055A is not equipped with a holding brake.
An optional holding brake is available for the product types ST0075A and ST0140A.
