Used if a motor output choke is used or for multiple motor
applications or high speed motor applications

PM motor vector speed control
AC Permanent Magnet (ACPM) motor control
3
BLDC motor vector speed control
Brushless DC motor control
4
SR motor vector speed control
Synchronous Reluctance motor control
5

This document only covers Simple vector speed control mode and V/f mode.
Motor Autotune – P-52
Setting
Description
Explanation
0
(Default)
Disabled
1
Enabled
Ensure all motor parameters are set correctly before carrying out an autotune.
P-07 – Motor rated voltage
P-08 – Motor rated current
P-09 – Motor rated frequency
NOTE: For the majority of applications, especially high inertia loads (fans), P-10
(Motor rated speed) does not need to be set.
When enabled, the drive immediately carries out a non-rotating autotune to measure
required data for optimal motor operation.
NOTES:
•
The autotune should be carried out on a cold motor
•
If an autotune has been carried out and the motor or motor cable is changed, it is advisable to re-
autotune the drive to the motor
•
An autotune can be used when P-51 = 0 – Simple vector speed control mode
•
An autotune is not required when P-51 = 1 – V/f mode.
•
If a motor output choke is used, V/f mode must be used – P-51 = 1 (V/f control)
•
If multiple motors are connected to the output of the drive, use P-51 = 1 (V/f control)
•
If high speed motors are connected to the output of the drive, use P-51 = 1 (V/f control)
Maximum current limit – P-54
As default, the current limit set in P-54 is 150% for P-13 = 0 or 110% if P-13 = 1 or 2.
The current limit is a % of motor rated current set in P-08. So when P-08 is reduced from its default value to
match the motor nameplate value, the current limit follows P-08.
P-54 can be set to 0. This means that the current limit is set to 150% of drive rated current (default setting of
P-08).
This can allow a higher peak current to be achieved where the motor rated current is less than the drive rated
current for applications which require a high, short term peak current on starting.
