(2) Speed Control (Uniform Speed Operation)
•
This controls the speed by the setting speed until deceleration stop command(POSCTR) is entered after execution by
POSVEL command..
•
The speed can be changed by the speed override instruction(POSSOR)
•
Speed control contains 2 types of start method : Forward direction start and Reverse direction start.
- Forward direction : when position address is positive number (+) (“0” included)
- Reverse direction : when position address is negative number (-)
Forward direction
Reverse direction
Set second operand of POSVEL instruction to 0 Set second operand of POSVEL instruction to 1
•
Timing diagram
Please refer to the section ‘POSVEL’ for details.
(3) Synchronization control
•
After the execution of POSSYNC, the HSC input pulse speed is synchronized by the designated synchronization
scale.
•
Scale can be changed during the execution.
•
Setting range: 0 ~ 100%
