When Position Control is configured at the Host
When the servo drive conducts speed control and position control is conducted at the host controller, perform the
operation below,following the operation in Operation Procedure in Speed Control Mode (Pn005=H
.□□0□
).
Step Description Check Method and Remarks
9
Check the input signal circuit again, and check that
the speed reference input (between the V-REF+ and
V-REF-) is 0 V.
Refer to the above figure for input signal circuit.
10
Turn the servo ON input signal (/S-ON) ON.
If the servomotor rotates at an extremely slow speed,
refer to 4.5.3 Adjusting Reference
Offset , and use the reference voltage offset to keep the
servomotor from moving.
11
Send the command for the number of servomotor
rotations. Check the sent number of rotations, the
actual number of rotations by visual inspection, and
the Un004 (rotation angle)[pulse]
Refer to 5.1.6 Operation in Monitor Mode for how it is
displayed.
Un004(rotation angle)[pulse]: The number of pulses
from the zero point.
12
If the sent number of rotations and actual number of
rotations in step 11 are not equal, correctly set the
Pn200 (PG divided ratio) outputting the encoder pulse
from the servo drive.
Refer to 4.5.8 Encoder Signal Output for how to set
PG divided ratio (Pn200[P/Rev]):The
number of encoder pulses per revolution.
13
When the speed reference input is set to 0 V and
servo OFF status is entered, the trial operation for
position control with the host controller is completed.
