Com m unication w ith higher-level control and custom er’s
term inal b lock
A communications interface on the CU 3 20 Control U nit and the
TM 3 1 Terminal M odule and TB 3 0 Terminal B oard are provided
as standard for use as the customer interface.
Y ou can use this customer’s terminal block to connect the sy s-
tem to the higher-level controller using analog and digital sig-
nals, or to connect additional units.
To simplify configuration and commissioning of the drive, the
TM 3 1 Terminal M odule can be preset to a variety of factory de-
fault settings.
O pen-loop and closed -loop control fu nctions
The converter control contains a high-quality sensorless Vector
Control w ith speed and current controls as w ell as motor and
converter protection.
S oftw are and p rotection fu nctions
The softw are functions available as standard are described be-
low :
1)
F actory setting: not activated (can be parameteriz ed)
S oftw are and p rotec tion fu nc tions
S etp oint inp u t The setpoint can be defined internally and ex ternally , internally as fix ed or motoriz ed potentiometer or jog
setpoints, ex ternally via the communications interface or an analog input on the customer’s terminal
block . The internal fix ed setpoint and the motoriz ed potentiometer setpoint can be sw itched over or
adjusted using control commands via all interfaces.
M otor id entific ation
Automatic motor identification permits fast and simple commissioning and optimiz ation of the drive control.
R am p -fu nc tion g enerator A user-friendly ramp-function generator w ith separately adjustable ramp-up and ramp-dow n times,
together w ith adjustable rounding times in the low er and upper speed ranges, improves the control
response and therefore prevents mechanical overloading of the drive train. The ramp-dow n ramps can
be parameteriz ed separately for emergency stop.
V
d c m ax
c ontroller The V
dc max
controller automatically prevents overvoltages in the DC link if the set ramp-dow n ramp is too
short, for ex ample. This may also ex tend the set ramp-dow n time.
Kinetic b u ffering (KIP) Line voltage failures are bridged to the ex tent permitted by the k inetic energy of the drive train. The
speed drops depending on the moment of inertia and load torque. The current speed setpoint is resumed
w hen the line voltage returns.
A u tom atic res tart
1)
The automatic restart sw itches the drive on again w hen the pow er is restored after a pow er failure, and
ramps up to the current speed setpoint.
F ly ing res tart
1)
The fly ing restart permits bumpless connection of the converter to a rotating motor.
T ec hnolog y c ontroller The "technology controller’s" function module allow s simple control functions to be implemented, e.g.
level control or volumetric flow control. The technology controller is designed as a P ID controller, w hereby
the differentiator can be sw itched to the control deviation channel or the actual value channel (factory set-
ting). The P , I, and D components can be set separately .
F ree fu nc tion b loc ks U sing the freely programmable function block s, it is easy to implement logic and arithmetic functions for
controlling the SINAM ICS G150 unit. The block s can be programmed by means of an operator panel or
the STAR TE R commissioning tool.
Drive Control Chart (DCC) Drive Control Chart (DCC) is an additional tool for the easy configuration of process-oriented functions for
the SINAM ICS G150. The block library contains a large selection of control, arithmetic and logic block s
as w ell as ex tensive open-loop and closed-loop control functions. The user-friendly DCC editor enables
easy graphical configuration and a clear representation of control loop structures as w ell as a high
degree of reusability of ex isting diagrams. DCC is an add-on to the STAR TE R commissioning tool
(
# Tools and configuration).
I²t d etec tion for m otor p rotec tion The motor temperature is calculated in a motor model stored in the converter softw are, tak ing into
account the current speed and load. M ore ex act sensing of the temperature, also tak ing into account the
influence of the ambient temperature, is possible by means of direct temperature sensing using K TY 84
sensors in the motor w inding.
E valu ation of m otor tem p eratu re M otor protection by evaluating a K TY 84 or P TC temperature sensor. W hen a K TY 84 sensor is connected,
the limit values can be set for alarm or shutdow n. W hen connecting a P TC thermistor, the reaction follow -
ing triggering of it (alarm or shutdow n) can be defined.
M otor b loc king p rotec tion A block ed motor is recogniz ed and protected against thermal overloading by shutting dow n.
