Setting Method For Synchronous Encoder - Mitsubishi Electric R32MTCPU Programming Manual

Setting method for synchronous encoder

Via module
■Setting method
Used to operate an encoder that is connected to a high-speed counter module, etc. controlled by Motion CPU as the
synchronous encoder axis.
By setting "1: Via module" in "[Pr.320] Synchronous encoder axis type", and setting "[Pr.331] I/O number" and "[Pr.332]
Channel number" of a module, the encoder value is acquired via the module controlled by the Motion CPU and controls the
synchronous encoder axis.
The encoder value can be used as a cycle counter within the range from 0 to (Resolution of synchronous encoder via module/
device - 1).
Connect the synchronous encoder to the I/O number, channel number assigned to high-speed counter module set in GX
Works3.
When the synchronous encoder axis connection is valid after Multiple CPU system's power supply ON, "Synchronous
encoder axis current value", "Synchronous encoder axis current value per cycle" and "Counter enabling status" will be as
follows.

High-speed counter module 0
■Setting of high-speed counter module
Set the high-speed counter module which connects the synchronous encoder as follows.
• Setting of GX Works3
Set the self Motion CPU as the control CPU in control CPU setting.
[System Parameter]  [I/O Assignment Setting]  "Control CPU Setting"
• Setting of MT Developer2
Set the following in the detailed settings of the module.
Press the "Detail" button in "Setting item" in [R Series Common Parameter]  [Module Configuration List]

Counter operation mode
If a fault is detected when the above setting is checked during initialization of a Motion CPU, a moderate error (error code:
30D1H) is output and the Motion CPU does not run.
Enabling the inter-module synchronization function for a high-speed counter module will reduce fluctuation of
the input speed.
Details
Set to "Ring counter".
Set to "Pulses counter mode".
