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:

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:

-/+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].
