Mitsubishi Electronics FR-V500 instruction manual Setting, Output speed, Torque %, 10V

Biases and gains of speed setting termi- nals (Pr. 902 to Pr. 905, Pr. 917 to Pr. 920)

4.7Biases and gains of speed setting term inals (Pr. 902 to Pr. 905, Pr. 917 to Pr. 920)

Adjust the biases and gains of the speed setting No. 2, torque command No. 3 and multi-function No. 1 terminals.

The "bias" and "gain" functions are designed to adjust the relationship between the 0 to 10V input signal, which is externally input for the setting of output speed, torque or magnetic flux.

CAUTION

Torque command bias and gain can not be set by applying an external negative setting signal to the torque command No. 3 or No. 1 terminal.

<Setting>

There are the following three methods to adjust the speed setting voltage bias and gain.

1)Method to adjust any point by application of a voltage to across terminals 2(1)(3) - 5

2)Method to adjust any point without application of a voltage to across terminals 2(1)(3) - 5

3)Method that does not adjust the bias voltage

(Example) Pr. 903 "speed setting No. 2 gain"

(Pr. 902 to Pr. 920 can be adjusted in the similar manner.)

<Adjustment procedure> Using the speed setting signal from the operation panel (FR-DU04-1) to make speed setting

(1) Power on (monitoring mode)					(2) Choose the PU operation mode.
