8.2.5 Phase synchronism
Purpose
z Drive concept for positive movements (e.g. packing of bottles on conveyor belts)
z Electrical shaft (e.g. vertical shaft, printing machines with embossing or printing rolls
depending on the format).
Conditions
Configuration C0005 = 6XXX or 7XXX.
In the configurations C0005 = 5XXX the specifications only apply to the slave 0.
Phase synchronous operation
When the phase controller is active, every controller can perform phase-synchronous, driftfree phase
synchronism. Since in the master frequency cascade the setpoint of the second slave is conditioned
in the first slave and both systems are not synchronous, a fixed phase offset develops which,
however, does not add up over time.
8.2.5.1 Phase controller
Phase controller adaptation
A value at MCTRL-P-ADAPT affects the gain set in C0254.
Special features
The difference between setpoint and actual phase is supplied to the phase controller. With reference
to the phase it is designed as P controller. Its influence can be set via C0254. C0254 = 0 means the
complete disconnection of the phase controller from the control system.
Setting range of C0254 = 0.0001
…
3.9999; C0254=1.00 and 16384 INC control difference
(1/4 revolution) correspond to a speed change of n
max
.
The output of the phase controller can be limited via C0472/6. The limitation can also be connected
with another analog signal source.
Phase controller limit
The phase controller limit is fixed to a phase difference of 65531 revolutions. If this phase difference
is exceeded, the phase controller cannot balance the setpoint anymore. When reaching the phase
controller limit, a TRIP P13 is generated. The error message can be evaluated according to its priority.
Tip!
When reaching the phase controller limit and monitoring is switched off, the sign at the phase
controller output may reverse.When setting CINH, the phase difference is set to zero.
