Indramat MAC Motors

The MAC servo motor is typically used as a variable-speed drive within a position control loop of a Numerical Control (NC) system, where it receives speed set-points from the NC. It boasts several application-specific functions, including high short-time acceleration moments and torque reduction through an 'I(red)' input, beneficial for lessening mechanical system load and for achieving controlled stops. It also supports torque-controlled operation for synchronizing two motors in a master/slave configuration, and can reverse rotation while maintaining set-point polarity. Speed set-points can be provided through differential input or two summing inputs with a zero voltage reference. Additionally, users can externally adjust drift offset with a potentiometer and monitor the equipment's 'ready' state via a potential-free relay contact. The motor allows for easy diagnostics and troubleshooting through its front panel. All adjustment parameters are pre-set using the MOD programming module, negating the need for time-consuming calibration, as the servo drive's control parameters are pre-optimized for coupled masses.

Ambient Temperatures

The technical data for the output are specified for operation within an ambient temperature range of 0 to 45 degrees Celsius and at an installation elevation from 0 to 1000 meters above sea level. MAC motors are designed with housings and covers that comply with DIN 40 050 standards, ensuring they are safeguarded against accidental contact with any moving or live parts, as well as against the intrusion of foreign objects and water.

Below is a breakdown of the IP (International Protection) numbers.

First digit Protection against contact and extrinsic objects
0 Little or no protection.
1 Protection against penetration by extrinsic objects with a diameter exceeding 50 mm. No protection against direct access, e.g., by a hand. Will keep larger body surfaces out, however.
2 Protection against penetration by extrinsic objects with a diameter exceeding 12 mm. Will keep fingers or similar objects out.
3 Protection against penetration by extrinsic objects with a diameter exceeding 2.5 mm. Keeps out tools, wiring, or similar objects thicker than 2.5 mm.
4 Protection against penetration by extrinsic objects with a diameter exceeding 1 mm. Keeps out tools, wiring, or similar objects thicker than 1mm.
5 Protection against damaging dust. Complete penetration by dust is not prevented, but the dust may not be permitted to penetrate to the extent that the operation of the electrical equipment is in any way hindered (protected against dust).
6 Protection against the penetration of dust (dust-free). Complete protection against penetration by extrinsic objects.
Second digit Protection against Water
0 Little or no protection.
1 Protection against vertically dripping water (dripping or trickling water). It may not have any destructive effects.
2 Protection against vertically dripping water. It may not have any adverse effects on electrical equipment tilted up to 15° in contrast to its normal position (water dripping or trickling at an angle).
3 Protection against water falling at an angle of up to 60°. Does not permit any damaging effects (sprayed water).
4 Protection against water sprayed at the equipment (housing) from all directions. Does not permit any damaging effects (splashwater).
5 Protection against a jet of water sprayed from a nozzle onto the equipment (housing) from all directions. Does not permit any damaging effects (jet of water).
