7.11.3 Setting of interpolation operation, pulse rate and feed rate
1. Linear Interpolation Operation (including the Interrupt Stop)
When setting a different pulse rate/feed rate (X-axis) and pulse rate/feed rate (Y-axis) during interpolation
operation
• If the 20SSC-H version is earlier than Ver.1.20
Set ratios that are the same for the pulse rate to the feed rate for the X-axis and the Y-axis.
When the ratios are different, the actual speed does not match the set speed.
• If the 20SSC-H version is Ver.1.20 or later
Set the interpolation gear ratio selection function in the X- axis, Y-axis.
2. Circular Interpolation Operation
When setting a different pulse rate/feed rate (X-axis) and pulse rate/feed rate (Y-axis) during interpolation
operation
• If the 20SSC-H version is earlier than Ver.1.20
Circular arcs are deformed if the ratio of the pulse rate to the feed rate differs between the X-axis and the
Y-axis. Set ratios that are the same for the pulse rate to the feed rate for the X-axis and the Y-axis.
• If the 20SSC-H version is Ver.1.20 or later
Set the interpolation gear ratio selection function in the X- axis, Y-axis if the ratio of the pulse rate to the
feed rate differs between the X-axis and the Y-axis.
Interpolation gear ratio selection (The 20SSC-H Ver. 1.20 or later supports this method)
Use the interpolation gear ratio selection function when setting different pulse rate/feed rate (X-axis) and
pulse rate/feed rate (Y-axis) during interpolation operation.
Sets the interpolation gear ratio selection
To apply this function, set [BFM # 14002 b14] in the operation parameter 2 to ON (X-axis, Y-axis).
