9.2.1 Initial Setting
9.2.1.1 Creating Electronic Cam Data
There are two methods of creating electronic cam data.
Method 1: Use DTO instruction to create electronic cam data directly
Method 2: Use the electronic cam chart in PMSoft to draw the cam curve
Please refer to section 9.4 for more information.
9.2.1.2 Setting Terminals
 Input terminals
1. MPGA0/MPGB0: Pulse input terminal for Master. Max allowable frequency: 200 kHz
2. START0/PG0: Input terminal for enabling noncyclic electronic cam
 Output terminals
1. FP/RP: Output terminal for pulse output of electronic cam. Max output frequency: 500 kHz
2. CLR0/CLR1: Output terminal for electronic cam synchronized output signal. When D1839,
D1838 (PI) CP≦ (Current Position) of Master (X axis) D1843,≦ D1842 (PII), CLR0/CLR1 will
be ON. (For special application of CLR0/CLR1, please refer to section 9.3.)
