201 Time Axis Output
The output of the Time Function Generator. When the Time Function Generator is
enabled by Par 183 [PI Command] bit 1 [Enable] or Par 151 [Logic Command] bit 3 [Time
Axis En], the value of this parameter ramps from 0 to 1 at a rate determined by Par 200
[Time Axis Rate]. Conversely, when the Function Generator is disabled, the value of this
parameter ramps from 1 to 0.

204 LimGen Y axis Mx
Sets Par 207 [Limit Gen Hi Out] and Par 208 [Limit Gen Lo Out] when the absolute value
of Par 206 [LimGen X axis In] is greater than or equal to 1.
Units:
Default:
Min/Max: P.U.

0.0000/8.0000 ✓ ✓ Real
205 LimGen Y axis Mn
Sets Par 207 [Limit Gen Hi Out] and Par 208 [Limit Gen Lo Out] when the absolute value
of Par 206 [LimGen X axis In] is equal to 0.
Units:
Default:
Min/Max: P.U.

206 LimGen X axis In
The X axis input to the Limit Generator. Typically this parameter is linked to a speed
reference or to Par 201 [Time Axis Output].
Default:
Min/Max: 0.0000
-/+8.0000 ✓ ✓ Real
207 Limit Gen Hi Out
Displays the positive output of the Limit Generator. When Par 206 [Limit Gen X axis In] is
greater than or equal to 1, this value equals Par 204 [LimGen Y axis Mx]. When Par 206
[LimGen X axis In] is equal to 0, this value equals Par 205 [LimGen Y axis Mn]. For
values of X Axis input between 0 and 1, the value of this parameter is interpolated from Y
axis min and max values. Typically this parameter is linked to Par 191 [PI High Limit].
