WARNING
Applications with Synchronous motors are possible to a limit extent.
The following points must be observed:
Operation must be limited to a maximum of 480 V AC.
The measurement sensitivity should be set to mode 4.
In the measurement sensitivity modes 1 to 3 there is a risk of an undetected
wire break at terminal W and a potentially dangerous detection of a standstill
when the motor is running. For this reason, in applications with measuring
sensitivity 1 to 3, the behavior with the motor running and wire break at termi-
nal W should be checked.
At frequencies below 2.5 Hz and a wire break at terminal W, it is possible that
standstill is detected.
