ABB 3BSE006065SR1 Output expansion card

The ARS 2100 SE series servo drives have a current derating during nominal operation. The rated current and the time of the maximum allowed peak current of the servo drive depend on different factors. These factors are:  Output current level (the higher the output current, the shorter the allowed time)  Power stage clock frequency (the higher the clock frequency, the shorter the allowed time)  Electrical rotational frequency of the motor (speed multiplied by pole pair number; the higher the rotational frequency, the longer the allowed time) The last point (electrical rotational frequency) only applies to the ARS 2108 SE. For a better clarity, we only distinguish between electrical rotational frequencies less than 2 Hz and those over 3 Hz. For rotational frequencies lying in between these two values, interpolation is required. Therefore, in the following you will find two tables for the ARS 2108 SE: the first one applies to blocked or slowly rotated motors (electrical rotational frequency ≤ 2 Hz); the second one applies to faster rotated motors

Motor feedback connection [X2A] and [X2B]

 Different feedback systems can be connected to the ARS 2100 SE series servo drives via the universal encoder interface:  Resolver (interface [X2A])  Encoder (interface [X2B])  Incremental encoders with analogue and digital track signals  SinCos encoder (single-turn/multi-turn) with HIPERFACE®  Multiturn absolute encoder with EnDat The encoder type is determined in the Metronix ServoCommander® parameterisation software. The feedback signal is available via the incremental encoder output [X11] for master-slave applications. It is possible to evaluate two shaft encoder systems in parallel. Typically, the resolver for the current control is connected to [X2A], and for example an absolute encoder is connected to [X2B] as a feedback system for the positioning control.

Resolver connection [X2A] 

The 9-pin D-SUB connection [X2A] is used to evaluate standard resolvers. Single- and multi-pole resolvers are supported. The user can state the number of pairs of poles of the servo motor in the "Motor Data" menu of the Metronix ServoCommander® parameterisation program so that the ARS 2100 SE determines the speed correctly. The number of pairs of poles of the motor (P0Motor) is always an integer multiple of the number of pairs of poles of the resolver (P0Resolver). Wrong combinations such as, for example, P0Resolver = 2 and P0Motor = 5 lead to an error message during motor identification. The resolver offset angle, which is determined automatically during the identification, is readable and writeable for service purposes.
