8 Operation
8.1.2 Trial Operation for Servomotor without Load from Host Reference
8-12
„ When Position Control is configured at the Host
When the SERVOPACK conducts speed control and position control is conducted at the host controller, perform the oper-
ations below, following the operations in (2) Operating Procedure in Speed Control Mode (Pn000 = n.
†† 0 † ) on the pre-
vious page.
Step Description Check Method and Remarks
9 Check the input signal circuit again, and check that
the speed reference input (voltage between the V-
REF and SG) is 0 V. Refer to the above figure for input signal circuit.
10 Turn ON the servo ON (/S-ON) input signal. If the servomotor rotates at extremely slow speed,
refer to 8.5.3 Adjusting Offset, and use the reference
voltage offset to keep the servomotor from moving.
11 Send the command for the number of motor rotation
easy to check (for example, one motor revolution)
from the host controller in advance, and check the
sent number of rotation and actual number of rota-
tion by visual inspection and the Un003 (rotation
angle 1)[pulse]. Refer to 7.1.3 Basic Mode Selection and Operation for
how it is displayed.
Un003 (rotation angle 1)[pulse]: The number of pulses
from the zero point.
12 If the sent number of rotation and actual number of
rotation in step 11 are not equal, correctly set the
Pn201 (PG divided ratio) outputting the encoder
pulse from the SERVOPACK. Refer to 8.5.7 Encoder Signal Output for how to set.
PG divider (Pn201 [P/Rev]): The number of encoder
pulses per revolution
13 When the speed reference input is set to 0 V and
servo OFF status enters, the trial operation for posi-
tion control with the host controller is completed. −
