12.6.5 Advance Angle Correction Function

"Advance angle correction function" is a function to correct the delay in the response of a
machine system connected to an electronic cam output or the delay in a PLC arithmetic
processing time. This function is available for the unit of Ver.1.5 or later.
 Specification of advance angle correction amount
• Advance angle correction amounts are specified for each slave axis using a tool software or
user program.
• By setting "advance angle correction reference speed" and "advance angle correction
reference amount", a correction amount is automatically calcuated using an active "master
axis input speed". The advance angle correction amount is calculated by the following
formula.
Advance angle
correction amount
Master axis input speed: Speed information after clutch control
 Internal processing of advance angle correction
The phase of the master axis which will be a reference of slave axis correction is obtained as
operation data for according to the set values of advance angle amount. A correction amount
for each slave axis is calculated based on this value as a reference.
