The actuation of a message or an alarm is shown on the top line of the
display unit, along with the general warning icon blinking on the top in the
icon side bar.
6.1 MESSAGES
Messages generally are meant to informing the operator on special states
reached by the device.
“Messages” are different from “alarms” in that the orange (front and rear)
lights do not blink and the SPIN continues operating normally.
Since software release 4.23 – 3.65, the orange lights have been performing
a quick triple flashing.
6.1.1 “I2T”
Indication of limitation for motor “I2T” (I square T).
It occurs when the average current absorption is too high and the device
limits the current supply to the motor. Work is still possible, but performance
will be reduced until the absorption regains the safety range.
6.1.2 “DecUnderflow”
This message shows up when, after a number of decrease commands, the
minimum reference tension threshold is reached.
It will automatically disappear when the accumulated “increases” and
“decreases” of the set tension are zeroed. This will also occur when the
device is turned off either in the Hardware and in the Software mode.
6.1.3 “IncOverflow”
It shows up when the minimum reference tension threshold is reached,
following a number of increase commands.
It will automatically disappear when the accumulated “increases” and
“decreases” of the set tension are zeroed. This will also occur when the
device is turned off either in the Hardware and in the Software mode.
