COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
1.3.9
IRMS LIMIT [mA]
2
Current limit value, calculated by the driver in order
to generate the error 18. The driver takes into
consideration the lowest rms current value among
the current values of the motor and of the driver.
This value is considered as the maximum limit value.
In this menu, the rms limit current (*) can be set up
to the maximum value.
By confirming the set value, it is possible to apply an
approximation.
Error 18 occurs when the motor torque exceeds the
maximum torque set for a longer time than the pre-
set time [1.3.5]:
When the current level exceeds the maximum value
(*), the timer increases. When the current returns
below the maximum level, the timer decreases. If
the timer exceeds the pre-set value (**), the error
signal is enabled. This is a safety function that the
user has at his disposal in order to protect the
application.
1.3.10
I TIME LIMIT[mS]
2
Time limit for exceeding the limit current(**).
This is the time limit for the generation of error 18.
1.3.1
DIRECTION
2
Motor rotation direction. This parameter enables you
to adjust the motor rotation direction to the pre-set
reference.
Options=Normal, Inverted.
1.3.12
CHECK 3PH LINE
3
It enables the check of absence of one or more
phases of input line voltage.
Options=Enabled, Disabled.
1.3.13
PWM FREQ
[Khz]
3
It sets the switching frequency of the motor output;
the higher the frequency is, the more the energy
losses are, causing the motor heating; the higher
the frequency is, the lower is the noise generated by
the switching.
Options= 4, 8, 10, 12, 16 kHz.
