If the following absolute encoder alarms are displayed, cancel the alarm by using the same method as
the set
up (initializing) with Fn008. They cannot be canceled with the SERVOPACK alarm reset input signal (/
ALM-RST).
Encoder backup error alarm (A.810)
Encoder checksum error alarm (A.820)
Any other alarms (A.8xx) that monitor the inside of the encoder should be canceled by turning OFF the
power.
2. Procedure for Setup
Follow the steps below to setup the absolute encoder.
Read Encoder Output Pulse Parameter
If using Fully-closed Loop Control with External Absolute Encoder use 1048576 for the Encoder Counts
and skip this section.
Read the number of encoder pulses per revolution in parameter Pn212. Now we need to multiply the encoder
pulses by 4 to convert them to encoder counts.
Example:
Encoder Pulses - Pn212 = 4096
Encoder Counts - 16384 = 4096 * 4
Now we can enter the calculated value into the Control parameter "Encoder Counts Per Rev Motor x" under the
Absolute Encoders section.
Software Setup
Navigate to the
Control Parameters
and enter Absolute Encoder into the filter box. To enable Absolute
