4
Set a smaller value about 500 in parameter 152.0(speed limit value) to limit the speed.
5
Make the SVON input of drive ON to start the motor excitation. (Connect the I 1 terminal to the COM-)
6
Input the analog torque command voltage at a low voltage to make the motor run at a low speed.
7
Improve the analog torque command voltage gradually after confirming the safe implementation of actual
operation. Set the actual value in parameter 152.0(speed limit value).
Note1: The control power supply for the models of 750W or less are supplied by external 24V DC. 1kW or more are supplied
from internal. So the control power supply of models of 1kW or more can be ON or OFF by switching on or cutting off the main
circuit AC power.
5.6 Position control mode(Internal position command)
Set the following parameter of control mode selection and command mode selection to come into the internal position
command mode. Use the locator to test run.
Table 5.6.1 Parameter of control mode change(Internal position command)
Parameter No.
Parameter
Description
2.0
Select control mode
Set to “0”.
3.0
Select command mode
Set to “3”.
5.6.1 Locator function
Execute the positioning according to the I/O command from the host control device, such as PLC. Set the Point Table in
HCX-SETUP and have the test run of locator function in HCX-SETUP.
5.6.2 Test run
Send the command from PC according to the steps, not the command from host control device(such as PLC), and have the
test run, such as back and forth movement.
Use HCX-SETUP to have the test run.
For details, refer to 「HCX-SETUP User’s Manual」.
5.6.3 Precautions
1) Alarm code No.10 「Position command overflow/ Home position reset failure」will happen in the following two conditions.
1. Out of the range of -1, 073, 741, 823～+1, 073, 741, 823 「Command unit」
2. 「Internal position command - Overflow detection option」(Parameter No.643.0) is set to “1=Enable”
Considering the above factors, please set 「Internal position command - Overflow detection option」(Parameter No.643.0)
according to the following table.

Test run
Note 1) The home position in the drive may disappear sometimes. Please reset the home position after parameter setting.
2) Please set 「Selection of Auto interpolation for command division and multiplication」(Parameter No.32.2) to “1=Enable”.
Initial value is “1=Enable”. When “0=Disable” is set, the speed change will become large.
