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".
