Program Example for Preset Mode
This section explains a program example for a system using counter 1 in pre-
set mode.
Note
After writing a program, make sure that the program works properly.
System Configuration
Cutting Cable at the Target Position
Operation
In this operation, only the prescribed length of cable is fed, and a cutter is acti-
vated to cut the cable at the target position.
Control Procedure
1,2,3...
1.
The brake is released and the motor is started at low speed.
2.
The motor speed is increased.
3.
Before reaching the target position, the motor is slowed back to low speed.
4.
The motor is stopped ahead of the target position, taking into account the
travel distance due to momentum.
5.
The brake is turned ON just before the target position.
6.
When the target position is reached, the cutter is activated.
Offset phase inputs multiplied by 2 are input to the encoder.
BCD data is used in the system.
The counter is reset at the rising edge of the internal reset (in mode 0).
Use an Encoder Conversion Adapter
to connect line driver outputs from an
encoder with open collector outputs.
