1. N i a SKA 2 2 Typical System Wiring Please refer to www exlar com for information on connectors and wiring 2 3 Feedback Information GSM Series actuators incorporate a quadrature incremental encoder with commutation signals as the primary rotary feedback device The alignment of this feedback device is dictated by the amplifier that the end user chooses for operating the actuator This amplifier is indicated in the model number of the GSM Series actuator as a 3 digit code consisting of 2 letters and 1 number Each amplifier has specific requirements for the feedback on the motor Not all encoder based amplifiers can use the same encoder encoder alignment or relative direction of encoder rotation Many amplifiers offer software that allows the entering of parameters or the downloading of motor data files that dictate how the feedback must be set up on the motor Exlar can provide many of these data files or the proper parameters to enter Entering motor parameter data to some amplifiers may require assistance from the amplifier manufacturer GSM Manual doc 5 12 12 12 PN 29959 Exlar Corporation Rev M 952 500 6200 Feedback Alignment When Exlar manufactures a GSM Series actuator the prop2.

28. r internal holding brake The brake is held open by the supply of power to a magnetic mechanical clutch Whenever there is not power to the brake the armature 1s held in place to prevent the inverted roller screw from turning and prevent the output rod from back driving which therefore prevents the output rod from moving The holding brake is permanent magnet engaged and electrically released The mechanical advantage of the roller screw allows the holding brake to prevent back driving of the load The holding capacity of the brake 1s sufficient to hold the rated force of the actuator when used in grease lubricated units Historically Exlar actuators and motors with holding brakes provided a transient suppression diode wired internally to the actuator or motor With the changes in servo amplifier and control technology there are now instances where the diode is not required to be within the motor An example of this is a control system using a dedicated brake control relay containing transient suppression components Because of this change in technology Exlar now provides the transient suppression diode separately from the actuator for inclusion in the brake control circuitry as needed by the end user A schematic is provided below showing the typical use of the transient suppression diode brake Brake Gta Banded side of diode cathode connects S to Brak
