2.2.6 Angular synchronism
Purpose
l Drive concept for positive movements (e.g. packing of bottles on conveyor belts)
l 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.
Angle−synchronous operation
When the angle controller is active, every controller can perform angle−synchronous, drift−free
angular synchronism with regard to its setpoint. 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
angular offset develops between the motor shafts which, however, does not add up over time.
2.2.6.1 Angle controller
Angle controller adaptation
A value at MCTRL−P−ADAPT affects the gain set in C0254.
Special features
The difference between setpoint and actual angle is supplied to the angle controller. With reference
to the angle it is designed as P controller. Its influence can be set via C0254. C0254 = 0 means the
complete disconnection of the angle controller from the controlled system.
Setting range of C0254 = 0.0001 ... 3.9999, C0254=1.00 and 16384 INC system deviation
(1/4 revolution) correspond to a speed variation of n
max
.
The output of the angle controller can be limited via C0472/6. The limitation can also be connected
with another analog signal source.
Angle controller limit
The angle controller limit is fixed to an angular difference of 65531 revolutions. If this angular
difference is exceeded, the angle controller cannot balance the setpoint angle anymore. When
reaching the angle controller limit, a TRIP P13 is generated. The error message can be evaluated
according to its priority.
Note!
When reaching the angle controller limit and monitoring is switched off, the sign at the angle
controller output may reverse.When setting CINH, the angular difference is set to zero.
