data. This data is used for
calculating motor torque, motor
thermal protection, etc.
NOTICE!
This parameter cannot be adjusted while the motor is
running.
1-25 Motor Nominal Speed
Range: Function:
Size related [100 - 60000 Enter the nominal motor speed
*
RPM] value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.
NOTICE!
This parameter cannot be adjusted while the motor is
running.
1-28 Motor Rotation Check
Option: Function:
Following installation and connection of the
motor, this function allows the correct motor
rotation direction to be verified. Enabling this
function overrides any bus commands or digital
inputs, except External Interlock and Safe Stop (if
included).
[0] OFF Motor Rotation Check is not active.
*
[1] Enabled Motor Rotation Check is enabled.
NOTICE!
Once the motor rotation check is enabled, the display
shows: "Please Note! Motor may run in wrong direction".
Pressing [OK], [Back] or [Cancel] will dismiss the message
and display a new message: "Press [Hand On] to start
the motor. Press [Cancel] to abort". Pressing [Hand On]
starts the motor at 5 Hz in the forward direction; the
display shows: "Motor is running. Check if motor rotation
direction is correct. Press [Off] to stop the motor".
Pressing [Off] stops the motor and resets
parameter 1-28 Motor Rotation Check. If motor rotation
direction is incorrect, two motor phase cables should be
interchanged.

Function:
[ 0 - par. The jog speed is a fixed output speed at
4-14 Hz] which the adjustable frequency drive is
running when the jog function is
activated.
See also parameter 3-80 Jog Ramp Time.
Function:
[ 1.00 - Enter the ramp-up time, i.e., the
3600 s]
acceleration time from 0 RPM to
parameter 1-25 Motor Nominal Speed.
Choose a ramp-up time such that the
output current does not exceed the
current limit in parameter 4-18 Current Limit
during ramping. See ramp-down time in
parameter 3-42 Ramp 1 Ramp-down Time.

Function:
[ 1.00 - Enter the ramp-down time, i.e., the
3600 s] deceleration time from
parameter 1-25 Motor Nominal Speed to 0
RPM. Choose a ramp-down time such that
no overvoltage 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
parameter 4-18 Current Limit. See ramp-up
time in parameter 3-41 Ramp 1 Ramp-up
Time.

recommended minimum motor speed.
The motor speed low limit must not
exceed the setting in
parameter 4-13 Motor Speed High Limit
[RPM].
