<2> A fault or alarm in the temperature evaluation of the VSM is communicated to the downstream evaluation using special temperature values.
<3> As a result of the wire breakage monitoring the maximum temperature that can be measured is limited to approx. 175 °C.
<4> When using a PTC, a value exceeding 250 °C deactivates the warning resp. fault.
When using a KTY, a value exceeding 188.6 °C deactivates the warning resp. fault.
<5> Can only be used with chassis infeeds.
<6> The VECTOR drive object is assigned a dynamic index (p0150).
