TI[N] – Temperature indications array
Purpose:
Reports the drive temperature measurement:
TI[1] – reports the drive temperature in Celsius.
TI[2] – Reports the temperature at which the drive shuts itself with over-
temperature protection.
Drive temperature is measured every ~3 mSec.
It is useful to analyze the drive temperature characteristics during the application
development stages.
This feature can also serve as maintenance procedure during the machine lifetime.
The temperature is measured for over-temperature protection. The temperature
sensor works well in the 25 °C to 130 °C range. Below 25 c measurements may be out of
range and displayed as approximately 25 c .
Methods to obtain the temperature:
• Terminal command– query TI[1] by the host application.
• Record the temperature characteristic as a function of time by using the
Composer recorder. Map the “Temperature” record variable from the record-
mapping list.
• Using the drive’s user program to sense a certain temperature, perform some
of the following actions:
o
Stop the machine under control.
o
Reduce the current limits or change the motion profile.
o
Change a digital output level.
o
Transmit a CAN message to PLC or machine host.
Notes:
When the temperature reaches the critical level, the drive will automatically
shut down the power stage with a motor failure exception (MF=0xD000).
If the drive does not support this feature, the TI[1] command returns –55.
