• The rate of the current rise for the pole position identification can be adjusted proportionally in
. The Lenze setting "100 %" corresponds to the fixed rise rate setting of the software
versions < V4.0.
• The P component of the PI controller for the pole position identification can be adjusted in
. With the Lenze setting "0", the PI controller continues to work as an I controller (as in
the previous software versions).
• The I component of the PI controller for the pole position identification can be adjusted in
. Please observe the following notes:
• The variable Position.dnActualMotorPos can be used to monitor the deviation of the position
from the start position with the
function in »Engineer«.
• In order to be able to compensate a position deviation faster, first the reset time in
should be reduced. If this does not result in the desired behaviour, the proportional gain can
be increased in
• Ensure that the position control does not get unstable. We therefore recommend to use an I
controller.
• The pole position identification comprises a monitoring function for the follow-up control. If a
movement greater than the permissible movement set in
is detected by the encoder
system:
• the pole position identification procedure is aborted.
• the response parameterised in
(Lenze setting: "Fault") is activated.
• the error message "Pole position identification cancelled" is entered into the logbook of the
controller.
• In order to detect a non-permissible blocking of the machine, a positive and negative test angle
relative to the current position are defined after the identification. The machine must align
itself to these two test angles within a tolerance of 25 %. The size of the test angle corresponds
to the max. permissible movement set in
Stop!
If there is no temperature monitoring in the motor and/or the I
2
xt motor monitoring and
the maximum current monitoring are not parameterised correctly, the motor may be
permanently damaged when the current amplitude is set too high (e.g. to the maximum
value)!
Note!
If the current amplitude is set to 400 % in
>, the device utilisation (Ixt)
monitoring and/or one of the motor monitoring functions may respond and cause the
abort of the pole position identification.
