Programming Example2: Absolute SSI Encoder (27-bit)
Continued with the previous example, now if changing the incremental encoder to the 13-bit absolute SSI encoder, the
setting steps for DHCMEAS parameters are shown as follows.
1. Set the input interface of the channel 1 to SSI input in HWCONFIG
2. Set the value in Cnt/Rev to 8192, the value in Smpl to 1000 and the value in Avg to 10.
3. When M0 switches to ON, the counter would start to count and configure DHCMEAS parameters in module's
settings at the same time for measuring frequencies and speed, which the results would be updated in the display of
Freq and RPM every 1000ms.
4. While the motor is running and the speed of position changes of the absolute encoder with SSI is 4095 LSB/Sec, the
results would be displayed as 4095kHz in Freq and 30 rev/min in RPM. In this example, the encoder speed is the
motor speed, so the motor here would be 30 rev/min.
