Phase trimming
This adds a setpoint at DFSET−A−TRIM to the phase setpoint (see code C0536/3) and changes the
rotor position to the setpoint with the number of increments provided in either direction (drive is
leading or lagging). The phase is trimmed within a range of ±32767 increments (
¢ ±1/2 rev.). Every
analog signal can be used as a source.
l The input is done in increments (one revolution
¢ 65536 increments).
l When analog values are entered, 100% correspond to 1/4 revolution = 16384 increments.
l Extension of the setting range with a multiplier under C0529.
Phase offset
Addition of a fixed phase offset under C0252 to the setpoint of the drive.
Speed−proportional phase setting
Leading or lagging of the phase with rising speed.
l Enter a suitable setting in increments under code C0253.
l The set phase offset is reached at 15000 rpm of the drive (linear relationship).
3.2.44.3 Synchronising to zero track or touch probe
The synchronisation is selected under C0532.
l C0532 = 1, index pulse
– zero track of digital frequency input X9 and zero track by the feedback system set under
C0490 (not for resolver evaluation).
l C0532 = 2, touch probe
– via terminals X5/E4 (actual pulse) and X5/E5 (set pulse).
l C0532 = 3, zero pulse (setpoint) and TOUCH−PROBE (actual value)
– Zero track from the digital frequency input X9 for the setpoint and touch probe initiator via
terminal X5/E4 for the actual value.
)
Note!
All three modes provide the possibility to define a divisor factor for the actual pulses
with codes C0531 as well as for the setpoint pulses with codes C0535 (default
setting = 1). Hence, it is possible to e.g. evaluate every 10th actual pulse if C0531 =
10. The other 9 pulses are ignored.
Touch probe initiators can have delay times which cause a speed−dependent phase offset.
To take this angular offset into account, the response time [ms] of the initiators is converted into an
angular correction depending on setpoint speed DFSET−NOUT and then considered in the setpoint
angle. For this purpose, the response time [ms] must be converted into a correction value [Inc.] first.
l Set correction value for the phase offset under C0430.
l Formula for the input value in C0430/x:
Eingabewert in C0430 ńx + 16384 @ Ansprechzeit[ms]
l Please take the response time [ms] from the data sheet of the initiator or contact the
manufacturer.
