4 DATA USED FOR POSITIONING CONTROL
Pr. 4
Current feed value during speed control
Specify whether you wish to enable or disable the update of "Md. 1 Current feed
value" while operations are performed under the speed control (including the
speed-position and position-speed switching control).
0: No update
The current feed value will not change.
(The value at the beginning of the speed control will be kept.)
1: Update
The current feed value will be updated.
(The current feed value will change from the initial.)
2: Clear to 0 and no update
The current feed will be set initially to zero and not
updated. (The value be kept "0".)
Pr. 5
Speed limit value
Set the maximum speed for OPR control, positioning control and JOG operation.
The speed limit value is determined by the following two conditions.
•
Motor speed
•
Workpiece movement speed
Pr. 6
Bias speed at start
Set the minimum starting speed for OPR control, positioning control and JOG
operation. When using a stepping motor or like, set this speed to start the motor
smoothly. (A stepping motor does not start smoothly if the motor speed is low at
a start.)
Set a value not more than " Pr. 5 Speed limit value". If it is more than " Pr. 5
Speed limit value", the "Setting range outside bias speed" error (error code: 906)
will occur.
