Data Sheet AEM 30 www.pwb-encoders.com precision works better Description The AEM30 is an absolute magnetic multiturn encoder. It is a reliable low cost hollow shaft encoder which can be fixed quickly and easily onto different sizes of motor shafts. The encoder is developed for absolute positioning, for brushless motors of servo motors and steppers. The AEM30 is a real time system for high speed applications and rough environments. The encoder is available with three different interfaces: SSI or BiSS ® or SPI. Power supply and signals are provided by a 8 pin Molex connector. Main...

After assembly by the customer (see page 9/10) and after power on, the encoder can indicate the error „magnet lost“. This is caused by missing the magnet during the shipment and the assembly. For erasing the error, set the Pin „Error Reset“ high by a unique impulse (5VDC, ≥ 100ms). Then reboot...

Data Sheet AEM 30 www.pwb-encoders.com precision works better Interface: Data transfer: SSI The position data increases when the shaft rotates in the direction of clockwise Data transfer: BiSS (C-Mode) 0: These are additional bits to refill the singleturn bit length to 12 bit or 16 bit. The number of Zero-bits is depended of the Ordering code (see below). The value of these bits is low. Example: Ordering code: 21 Position bits + 3 x 22 Position bits + 2 x 23 Position bits + 1 x 24 Position bits 25 Position bits + 3 x 26 Position bits + 2 x 0 bits + ... 0 bits + ... 0 bits + ... +… 0 bits +...

Because AEM30 can output the sensor data (SD) immediately, the master can transmit the SDAD Transmission command directly. The sensor data in SPI are byte aligned. First comes 0-4 byte multiturn depending on the resolution, second are two bytes singleturn and at last one status byte including one error bit, one warning bit and six bits...
