It is important to set motor par. 1-2* correctly, since these
form part of the AMA algorithm. An AMA must be performed
to achieve optimum dynamic motor performance. It may
take up to 10min, depending on the power rating of the
motor.
NOTE
Avoid generating external torque during AMA.
NOTE
5 5
If one of the settings in par. 1-2* is changed, par. 1-30 to par.
1-39, the Advanced Motor Parameters, will return to default
setting.

synchronous motor speed n
a ramp-up time such that the output
current does not exceed the current
limit in 4-18 Current Limit during
ramping. The value 0.00 corresponds
to 0.01 sec. in speed mode. See ramp-

dependant] synchronous motor speed n
Choose a ramp-down time such that
no over-voltage arises in the inverter
due to regenerative operation of the
motor, and such that the generated
current does not exceed the current
limit set in 4-18 Current Limit. The
value 0.00 corresponds to 0.01 s in
speed mode. See ramp-up time in
