1. SUMMARY
1-1. Summary
This manual describes the specifications and instruction procedures for the VE-2CC/VM-2CC which is able to
connect to the open-architecture network "CC-Link".
VE-2CC/VM-2CC is a converter which can detect the machine's current position value by ABSOCODER.
The ABSOCODER sensor uses a magnetic position detection format, thereby the incremental format encoder
which has been used can be replaced to VE-2CC/VM-2CC.
This converter can be used for the automatic controlling which needs position detections, such as the conveyor,
press machine, assembly machine, packing machine and etc.
The detected position data can be read by the host controller via CC-Link, so the system is able to reduce the
wiring.
1-2. Features
Features of VE-2CC/VM-2CC
(1) Absolute position detection
An absolute position detection format ensures accurate position detection even if a power interruption
condition occurs. An origin returning operation is not required.
(2) High-resolution position detection
[1] VE-2CC: 8192 divisions / turn x 1 turn
[2] VM-2CC: 4096 divisions / turn x 32 turns (In the case of using MRE-32SP062)
If ABSOCODER that "the total number of turn" is twice as much as "MRE-32SP062" is used, the
number of divisions is 1/2 per turn.
(3) Connects with CC-Link
The position data, current position value setting data, and error signal can be sent or received on CC-Link.
(4) Self-diagnosis function
The following self-diagnosis result can be checked by the remote input (RX).
- Internal CPU error (watchdog timer error)
- Memory error
- Sensor error (The sensor is disconnected or severed.)
- Low-voltage detection
(5) Current position setting function
The position data can be designated as desired value from the host controller.
