range
0 to 1 – You can reverse the polarity of the speed command input signal (SPR:CN
X5, Pin-14). Use this function when you want to change the motor
<1>
rotational direction without changing the polarity of the command signal
from the host.
Setup value
<1>
<Notes>
• Default of this parameter is 1, and the motor turns to CW with (+) signal,
this has compatibility to existing MINAS series driver.
• When Pr06 (ZEROSPD) is set to 2, this parameter becomes invalid.
<Caution>
When you compose the servo drive system with this driver set to
velocity control mode and external positioning unit, the motor might
perform an abnormal action if the polarity of the speed command signal
from the unit and the polarity of this parameter setup does not match.
–2047 to 0.3mV • You can make an offset adjustment of analog speed command (SPR :
CN X5, Pin-14) with this parameter.
2047
• The offset volume is 0.3mV per setup value of "1".
<0>
• There are 2 offset methods, (1) Manual adjustment and (2) Automatic
adjustment.
1) Manual adjustment
• When you make an offset adjustment with the driver alone,
• when you compose a position loop with the host,
• Set this parameter up so that the deviation pulse may be reduced
2) Automatic adjustment
• For the details of operation method at automatic offset adjustment
• Result after the execution of the automatic offset function will be
–20000 to r/min When the internal speed setup is validated with parameter Pr05, "Switching
of internal or external speed setup", you can set up 1st to 4th speed into
20000
Pr53 to 56, 5th to 8th speed into Pr74 to 77 in direct unit of [r/min].
<0>
<Caution>
• The polarity of the setup value represents that of the internal command
speed.
• The absolute value of the parameter setup is limited with Pr73 (Setup of
–20000 to r/min
over-speed level)
