Response Level Of Analog Input And Noise Elimination - Mitsubishi Electric FR-E8AXY E KIT Instruction Manual

 Adjustment by only changing the torque without adjusting the gain voltage (Example of changing
the gain torque from 150% to 130%)
Operating procedure
1.
Selecting the parameter
Turn the setting dial or press the UP/DOWN key until "C18" (C18 (Pr.920)) appears.
Press the SET key to show the present set value. (150.0%)
2.
Changing the torque settings
Turn the setting dial or press the UP/DOWN key to change the value to "130.0". (130.0%)
Press the SET key to confirm the setting. "130.0" blinks.
3.
Selecting the mode and the monitor item
Press the MODE key three times to select the monitor mode and to monitor a frequency.
4.
Start
Turn ON the start switch (STF or STR) to apply voltage across terminals 1 and 5.
Operation is performed with 130% torque.
NOTE
• If the voltage values at the gain and bias torques are too close to each other, an error "Er3" may be indicated.
• For operation outline of the parameter unit (FR-PU07), refer to the FR-PU07 Instruction Manual.
• Use the calibration parameter C16 (Pr.919) to set the bias torque.
CAUTION
• When setting a value other than "0" as the bias torque at 0 V, note that simply turning ON the start signal will supply torque to the motor even
if a torque command is not given.

Response level of analog input and noise elimination

The response level and stability of frequency command or torque command using the analog signal input via terminal 1 of the
FR-E8AXY can be adjusted as well as signal input via terminal 2 or 4 of the inverter.
For details, refer to the description of Pr.74, Pr.822, Pr.826, Pr.832, and Pr.836 (Analog input filter) in the FR-E800
Instruction Manual (Function).
