CUI Inc │ SERIES: AMT30 │ DESCRIPTION: MODULAR ENCODER date 03/25/2014 │ page 5 of 6 ENCODER OPERATIONAL MODE Initialization mode: ED – At power up the encoder goes through an initiation and stabilization procedure. This includes microprocessor stabilization and the program for combining Coarse and Fine channel of the encoder for getting the absolute start position. This takes less than 0.1 seconds. Tracking mode: U – MCU 12 bit position register is updated from Fine Asic every 48 μs. – The commutation program in the MCU has a compensation for the average delay caused by the update rate, leaving a remaining jitter of less than 24 μs RMS. •The communication jitter expressed in electrical degrees will be proportional speed and does not reach 6 deg RMS until the speed reaches the following values: Commutaon Jier in Electrical Degrees N 12 10 TI 8 6 4 2 0 0 N Jier (Electrical Degrees) 14 2000 4000 6000 8000 4 pole 6 pole 8 pole 10 pole 12 pole 20 pole 10000 O RPM COMMUTATION ALIGNMENT AND SETTING THE ZERO POINT IS C We strongly recommend the use of the AMT303 series demo board to set commutation zero. It greatly simplifies and expedites the process. The demo board also allows setting of resolution, # of motor poles, direction of quadrature increment, and commutation angle offset (when required). If you do not have or cannot obtain a demo board, use the following procedure to align the AMT303XX commutation angle with your motor: Mount the AMT303 series encoder to the motor. 2. Put the motor in a ‘locked rotor’ condition. Consult your motor manufacturer if you are not certain how to lock the rotor for commutation alignment. 3. With the motor in a locked rotor position, pull pin# 2 (zero set) low, tie Pin 2 to Ground, to write the rotor position into non-volatile memory in the encoder. 4. Power cycle the encoder, i.e., remove power from it. The commutation position is now permanently aligned with the motor rotor zero position and will use this offset at initialization every time at startup. Note: The procedure is based on the standard “WYE” motor phase connection configuration. If your motor uses other than the “WYE” phase connection, you must acquire the AMT303 series demo board to program the required offset to align encoder commutation signal zero with motor zero position.
