Chapter 9 Major Positioning Control
9.1.5 Control unit "degree" handling
When the control unit is set to "degree", the following items differ from when other
control units are set.
[1] Current feed value and machine feed value addresses
The address of "
Md.20
Current feed value" becomes a ring address from 0 to
359.99999
°
. The address of "
Md.21
Machine feed value" will become a
cumulative value. (They will not have a ring structure for values between 0 and
359.99999
°
.) However, "
Md.21
Machine feed value" is restored with cumulating
the machine feed value before the power supply OFF (the rounded value within
the range of 0 to 359.99999°) to the movement amount during the power supply
OFF at the communication start with servo amplifier after the power supply ON or
PLC CPU reset.

[2] Software stroke limit valid/invalid setting
With the control unit set to "degree", the software stroke limit upper and lower
limit values are 0 to 359.99999
°
.
(a) Setting to validate software stroke limit
To validate the software stroke limit, set the software stroke limit lower limit
value and the upper limit value in a clockwise direction.

1) To set the movement range A, set as follows.
• Software stroke limit lower limit value .................................. 315.00000°
• Software stroke limit upper limit value ................................... 90.00000°
2) To set the movement range B, set as follows.
• Software stroke limit lower limit value .................................... 90.00000°
• Software stroke limit upper limit value ................................. 315.00000°
(b) Setting to invalidate software stroke limit
To invalidate the software stroke limit, set the software stroke limit lower
limit value equal to the software stroke limit upper limit value.
The control can be carried out irrespective of the setting of the software
stroke limit.
