ATTENTION
L’application d’une tension supérieure à l’entrée maximale admissible au
connecteur d’entrée de signal de régime (SPEED) ou au connecteur d’entrée de
signal de couple (TORQUE) peut endommager l’instrument.
Revolution Signal Input Connector (SPEED)
Input the signal output from the revolution sensor (a DC voltage (analog signal) or a
pulse signal that is proportional to the rotating speed of the motor) according to the
following specifications.
