Make the following parameter settings in the same manner.
99.07 Motor nominal voltage
The allowable range is 1/6 ×

… 2 ×

N
of the drive.
With permanent magnet motors, the nominal voltage is the BackEMF voltage at nominal
speed. If the voltage is given in volt/rpm (eg. 60 V per 1000 rpm), the voltage at a nominal
speed of 3000 rpm is 3 × 60 V = 180 V. Note that nominal voltage is not the same as
equivalent DC motor voltage (EDCM) given by some manufacturers. The nominal voltage
can be calculated by dividing the EDCM voltage by 1.7 (or square root of 3).
99.08 Motor nominal frequency
With permanent magnet motors, if the nominal frequency is not shown on the nameplate,
it can be calculated using the following formula:
f
=
n
×
p
/ 60
where
n
= nominal motor speed,
p
= number of pole pairs.
99.09 Motor nominal speed
99.10 Motor nominal power
99.11 Motor nominal cosfii
99.12 Motor nominal torque
These values are not required, but can be entered to improve control accuracy. If not
known, leave at 0.
99.13 Identification run request
This parameter selects the mode of the identification run (DTC motor control mode only).
WARNING!
The identification run modes marked thus * will run the motor in the
forward direction (see below for details). Make sure it is safe to run the motor
before choosing any of these modes.
*Normal
mode should be selected whenever possible. The driven machinery must be de-
coupled from the motor if
• the load torque is higher than 20%, or
• the machinery is not able to withstand the nominal torque transient during the
identification run.
*
Reduced
mode should be selected if the mechanical losses are higher than 20%, ie. the
load cannot be de-coupled, or full flux is required to keep the motor brake open (eg. with
conical motors).
The
Standstill
mode should be selected if neither the
*Normal
or
*Reduced
mode can
be used.
Notes
:
• This mode cannot be used with a permanent magnet motor if the load torque is higher
than 20% of nominal.
• Mechanical brake is not opened by the logic for the identification run.
Ensure that the Safe torque off and emergency stop circuits (if present) are closed.
Start the identification run by pressing the
(Start) button.
A warning will indicate that the
identification run is in progress.
