9 Input 3 (REV enable) REV-EN Input 22 Phase-A- (LD) A- Output
10 Input 4
―
Input 23 Phase-B+ (LD) B+ Output
11 Input 5
―
Input 24 Phase-B- (LD) B- Output
12 Input signal common IN-COM Input 25 Phase-Z+ (LD) Z+ Output
13 Encoder Monitor ground MON-GND Output 26 Phase-Z- (LD) Z- Output
Note 1: OC: open collector port, LD: line driver port
Note 2: Function assignment can be performed for Inputs 4 and 5 (10, 11 pin).
Note 3: Logic change can be performed for the I/O signals other than Output 5 (Phase-Z OC output)
using “13: Input pin logic setting” and “14: Output pin logic setting” in “Parameter.”
Do not connect the pins with “-” in the Signal column to the external
device.
If you do, failure may occur because it is connected to the internal circuit.
