Programming
140
Wire the CPM2C outputs as shown in the following diagram.
01000: Pulse output 0
01001: Pulse output 1
The settings in the PC Setup related to synchronized pulse control are listed in
the following table.
Word Bits
DM 6642 00 to 03 High-speed counter input mode setting
0: Differential phase input 5 kHz
1: Pulse + direction input 20 kHz
2: Up/down input
4: Increment
04 to 07 High-speed counter reset method setting
0: Phase-Z signal + software reset
1: Software reset
08 to 15 High-speed counter setting
00: Do not use.
01: Use as high-speed counter
02: Use as synchronized pulse control
03: Use as synchronized pulse control
04: Use as synchronized pulse control
The settings will go into effect when the mode is changed (from PROGRAM to
MONITOR/RUN) or when the power supply is turned ON to the PC.
The following table shows the instruction operations related to synchronized
pulse control.
