Parameter Name and Description
080
Standard
Sets the method of speed regulation.
E C
Selects the source for motor speed feedback.
Note that all selections are available when you
are using Process PI.
"Open Loop" (0) - no encoder is present, and
slip compensation is not needed.
"Slip Comp" (1) - tight speed control is needed,
and encoder is not present.
"Encoder" (3) - an encoder is present.
"Simulator" (5) - Simulates a motor for testing
drive operation and interface check.
081 [Minimum Speed]
Sets the low limit for speed reference after
scaling is applied.
Refer to parameter 083 [Overspeed Limit].
082 [Maximum Speed]
Sets the high limit for speed reference after
scaling is applied.
Refer to parameter 083 [Overspeed Limit].
083 [Overspeed Limit]
Sets the incremental amount of the output
frequency (greater than [Maximum Speed]) for
functions such as slip compensation.
P82 [Maximum Speed] + P83 [Overspeed
Limit] must be 
