08-35=1 or 2
: The AC Drive will display [OH4 Motor Temp Warning] when the motor temperature increases and AI2
voltage level rises above the value set in 08-44. In this condition the motor will decelerate or coast to stop depending
on setting 08-35=1 or 2.
08-35=3
: The AC Drive will display [OH3 Motor Temp Warning] when the motor temperature increases and AI2
voltage level rises above the value set in 08-44. In this condition the motor will continue running. If AI2 voltage level
rises above the value set in 08-42 for the time specified in 08-39 the motor coasts to stop.
08-35=1, 2 or 3
: When the motor cools down and AI2 voltage
level falls below the value in 08-43, [OH3/OH4 Motor
Overheat] will reset.
Note:
The resistor (PTC)
according to the British
Standards Institution:
Tr is 150°C for Class F
and is 180°C for Class
H
Tr - 5°C : RT≤ 550Ω,
insert value of RT into
formula (1) and set 08-
43 to the calculated
value.
Tr+ 5°C: RT≥1330Ω,
put the value of RT in
formula (1), and set
08-44 to the calculated
value.
