8.2.7 Motor temperature
The motor temperature is monitored by means of a KTY. Connect the
thermal sensor to the resolver cable at X7 or the encoder cable at X8.
ƒ Warning threshold (OH7) can be set via C0121
– The switch−on point is 5 °C below the threshold set.
ƒ Fixed warning threshold (OH3) = 150 °C
– The switch−on point is 135 °C.
The response for the case when the thresholds are exceeded can be defined
in:
ƒ C0584 (adjustable threshold)
ƒ C0583 (fixed threshold)
(
Stop!
With the setting C0583 = 3, monitoring is deactivated. The
motor temperature in C0063 shows 0 °C, even if C0584 = 2
(warning) is set.
The SD6 fault is triggered if there is a short or open circuit between X7/8 and
X7/9 or X8/5 and X8/8.
The response can be set under C0594.
The motor temperature is monitored with a PTC thermistor or thermal
contact. Wire the temperature sensor to T1, T2.
ƒ Fixed warning threshold (OH8)
– The switch−off threshold and the hysteresis depend on the
temperature sensor (DIN 44081).
The response to exceeding the threshold can be set under C0585.
(
Stop!
Motor could be destroyed!
ƒ If the responses "Warning" or "Off" are set, the motor could be
destroyed by overload.
Protective measure:
ƒ Set the response "TRIP".
