Comment, note
Infeed Control
• Booksize
-
Current control with/without
mains sensor
-
V
DC
control with/without mains
sensor
• Chassis
-
Current control with mains
sensor
-
V
DC
control with mains sensor
• Booksize/chassis
-
Basic Mode
Rectification only
-
Smart Mode
Rectification and regenerative
feedback
• Mains identification
• Controller optimization
• Harmonics filter
• Automatic restart
The mains sensor is the VSM 10
Voltage Sensing Module; "current"
is the line current; 3-phase with
line frequency
Vector Control
• Asynchronous (induction) motor
-
Torque control with/without en-
coder
-
Speed control with/without en-
coder
• Torque motor
-
Torque control with encoder
-
Speed control with/without en-
coder
• Asynchronous (induction) motor,
torque motor
-
Position control with encoder
• Linear/parabolic characteristic
• Fixed-frequency characteristic
(textile)
• Independent voltage setpoint in-
put
• Data set changeover
• Extended setpoint input
• Motor identification
• Current/speed controller optimi-
zation
• Technology controller
• Basic positioner
• Automatic restart
• Flying restart with/without enco-
der
• Kinetic buffering
• Synchronization
• Droop
• Brake control
Mixed operation with
V/f
control
modes is possible; it is for this rea-
son that the
V/f
control modes are
stored only once in the "Vector
Control" drive object
Position control can be selected
as a function module from both
Servo and Vector mode.
Synchronous motors (1FK and
1FT) and linear motors can be
operated only in Servo mode.
Servo control
• Asynchronous (induction) motor
-
Torque control with encoder
-
Speed control with/without en-
coder
• Synchronous motor, linear motor
and torque motor
-
Torque control with encoder
