ATS 48 Soft Starter b
Soft start - soft stop unit is a controller with 6 thyristors which is used for the
torque-controlled soft starting and stopping of three-phase squirrel cage
asynchronous motors in the power range between 4 and 1200 kW.
It offers soft starting and deceleration functions along with machine and
motorprotection functions as well as functions for communicating with control
systems.
These functions are specially designed for use in applications such as pumps,
fans, conveyors, which are primarily to be found in the construction,
food & beverage and chemical industries. The highperformance algorithms of
the Altistart 48 contribute signicantly to its robustness, safety and ease of setup.
Contactor and circuit breaker could be replaced by a TeSys U controler associated
with a specic module for soft starter or variable speed drive.
ATV 31 variable speed drive b
is a frequency inverter for single and 3-phase squirrel cage asynchronous motors
rated between 0.75 and 15kW.
The Altivar 31 is robust, compact and easy to use. It incorporates functions that
are suitable for the most common applications, including pumps, fans, conveyors,
mixers...
Modbus and CANopen protocols are integrated into the ATV31 as standard.
Altivar 31 drives are supplied with a heatsink for normal environments and
ventilated enclosures. Multiple units can be mounted side by side to save space.
ATV61 variable speed drive b
is a frequency inverter for 3 phase asynchronous motors rated between 0.75 and
630kW.
The Altivar 61 includes specic functions for pumping and ventilation application:
energy saving -
automatic catching of a spinning load with speed detection -
adaptation of current limiting according to speed -
noise and resonance suppression (adjustment of switching frequency) -
Integrated PID regulator -
Electricity and service hours meterdetection of absence of uid, -
detection of zero ow rate, limiting of ow rate -
customer settings with display of physical values (bar, I/s, °C, “etc”) -
The contactor and the circuit breaker can be replaced by a TeSys U controller. -
TeSys T motor management system b
The capability of over-current relay is limited when problems associated with volt-
age, temperature or special applications must be taken into account.
TeSys T provides complete management of the motor and its load. It incorporates
below functions:
current and voltage sensors -
hybrid analog and digital electronic technology, -
the use of communication buses for data exchange and control, -
powerful motor modelling algorithms, -
application programs whose parameters can be set. -
