COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
7.2.6.3
Sercos II Cosmos
If you use the SERCOS controller, it is not necessary to set the following parameters, because this operation is directly
performed by the control unit, which sends specific messages. The data modified by the user, concerning the SERCOS
interface will be overwritten.

This section includes the controller setting and the
parameters concerning the driver control system.
1.3.1
CONTROLLER
3
It determines the driver control mode.
Options=Sercos, Analog and Service.
1.3.2
TORQUE LIMIT[Nm]
2
Torque limit that the motor can generate in this
application; this datum must be lower than the max
torque indicated by the motor manufacturer and set
in the parameter TORQUE MAX [1.4.7]; please, also
refer to parameter KT [1.4.17] in order to determine
the max current required by the motor.
Min=0.00Nm, Max=+58.00Nm.
1.3.3
SPEED LIM+ [rpm]
2
Motor speed positive limit
Min=0rpm, Max=+7000rpm.
1.3.4
SPEED LIM- [rpm]
2
Motor speed negative limit.
Min=0rpm, Max=-7000rpm.
1.3.5
TORQUE LIM TIME
[s]
2
Torque limit time: if the motor torque exceeds the
limit value set in TORQUE LIMIT [1.3.2], a timer is
increased; as soon as the torque decreases below
the limit, the timer will be decreased.
If the total time indicated by this timer exceeds the
value set in this parameter, the error “Torque time
limit overtaken” will be displayed.
In other words, a heavy load for a longer time than
the limit value will cause the motor disabling and the
generation of an error status.
Thanks to this datum, it is possible to find out jams
and/or collisions of mechanical components.
Min=0.0s, Max=+32.0s.
