Parameters Details
Select the analog monitor output voltage direction.
When monitor type is motor speed and gain of conversion is 500 (1 V = 500 r/min)
Adjust the offset of the speed command input (REF: CN1 pin 14).
The offset amount is approx. the set value times 0.359 mV.
There are 2 ways to adjust the offset.
• Manual adjustment
• Automatic adjustment
The manual adjustment is as follows:
• To adjust the offset for individual drivers, accurately input 0 V to the speed command input/torque command input
(REF/TREF1) (or connect to the signal ground), and then set this parameter so that the motor does not rotate.
• If you use a position loop in the host device, set this parameter so that there are no
accumulated pulses at servo lock stop status.
The automatic adjustment is as follows:
This parameter will be automatically set when automatic offset adjustment is executed. Refer to
"Analog Input Automatic Offset Adjustment" (P.9-26) for the automatic offset adjustment method.
