127.4
Max. current notch position
The maximum current, which is permitted at notch position search.
The value results from the lower value of:
– Current set value Notch position search (
Z
19.51
–
) * Motor rated torque current
(
Z
19.10
–
).
– 60 % of the power unit's rated current, if PWM frequency was set
Z
130.15
–
).
127.5
Current rise
Current increase in unit A/s for notch position methods 0 and 1
127.6
Current drop
Current drop in unit A/s for notch position methods 0 and 1
127.7
Duration constant current
Here the minimum length of time of the constant current phase at notch position search
method 0 and method 1 is set.
This time remains in the end position at maximum current (
Z
127.4
–
). Now Notch position
calculation (
Z
127.8
–
) can be initiated.
127.8
Notch position electrical
The notch position electric (or pole position offset, commutation angle offset) is the fixed
angular difference or offset between the pole position referring to the supplying coordi-
nate system and the encoder angle actual value (of the encoder, being responsible for
the motor control).
NOTE!
The requirements, which are described in the Danger note on
Z
page 622
–
must be
complied with in order to operate correctly.
At first the drive components must be checked. This includes the wiring, the motor
encoder with its parameterization and the setting of the motor parameters (rotary
field, pole pair numbers …).
