17 TCF DISPLAY MESSAGES
The following describes the various displays and messages that can appear on the TCF drive .
17 .1 SPEED/TORQUE DISPLAY
If the drive is in a STOP state (indicated by "- - -" on the display), and the commanded
speed/torque is changed using the keypad (s and t buttons), the display will show the
commanded speed/torque, and after a few seconds it will begin to alternate between the
commanded speed/torque value and "- - -" . If the
Mode button is pressed, the display will
stop alternating and show "- - -" only .
When the drive is given a START command, the displayed speed will start increasing as the
drive accelerates up to the commanded speed/torque . If the commanded speed/torque value
is changed while the drive is running, the display will show the commanded value while it is
being changed, but then it will display the actual speed as the drive ramps up or down to the
new commanded value .
NOTE
• When the drive is running in the reverse direction, the upper decimal point
on the display will be illuminated .
• In VECTOR TORQUE mode (refer to Parameter 80), the torque reference
display will have the bottom two decimal points illuminated to distinguish
it from the actual speed display .
