Detail Drive Configuration and Operation Chapter 1
Two Position Floating Point Switch
Configuration:
• Parameter 1370 [Switch Control] bit 2 “SW Real 1 On” activates the
switch.
• The value of parameter 1374 [SW Real 1 NO] is moved into parameter
1376 [SW Real 1 Output] when bit 2 “SW Real 1 On” of parameter 1370
[Switch Control] is on.
• The value of parameter 1375 [SW Real 1 NC] is moved into parameter
1376 [SW Real 1 Output] when bit 2 “SW Real 1 On” of parameter 1370
[Switch Control] is off.
• [SW Real 1 Output] contains the value of either [SW Real 1 NO] or [SW
Real 1 NC].
Time Axis Generator
Ramps the output of the function generator at the rate in parameter 200 [Time
Axis Rate].
• When parameter 183 [PI Command] bit 1 “Time Lim En” or parameter
151 [Logic Command] bit 3 “Time Axis En” = 1 the output ramps from
0.0000…1.0000 at the Time Axis Rate set in [Time Axis Rate].
• When parameter 183 [PI Command] bit 1 “Time Lim En” or parameter
151 [Logic Command] bit 3"Time Axis En” = 0 the output ramps from
1.0000…0.0000 at the Time Axis Rate set in [Time Axis Rate].
