Editing Configuring IONI drive in SimuCUBE

{{SimucubeManualNav}}This page helps setting correct parameters to IONI drive.

== Preparations ==
# Download [[Granity]] software
# Connect SimuCUBE X4 to PC with USB cable
# Connect motor to connector X1 and motor feedback device to X16 as instructed earlier
# Have E-stop switch unconnected or open until configuration is complete
# Power on SimuCUBE
# Wait until windows has recognized the device and installed driver
# Start Granity software
# Connect to IONI by clicking Connect to drive button<br /> [[File:Granityconnect.png|830x830px]]
# Once list of found devices pop-up, select the IONI drive and click ''Open''
[[File:simucubeboxcabling_annotated.jpg|thumb|600px|Connections needed in this step are: AC, X1 (motor power and E-stop), X16 (encoder) and X4 (Granity USB). All others may be left unconnected.]]Each SimuCUBE system consists one [[IONI Servo & Stepper Drive]] that is controls the motor of [[Force feedback system (FFB)]]If everything went fine, we are now connected to IONI and change it's settings. If not, see [[SimuCUBE troubleshooting]] and [[Device connection troubleshooting]].

== Upgrading IONI firmware ==
First it is recommended to upgrade to the latest IONI firmware:
# Download latest IONI firmware from [[IONI firmware releases]]
# Follow instructions of [[Granity user guide/Uploading a firmware]]
# Connect again into drive by choosing ''Connect to drive'' just like we did first time
# Proceed to ''Loading motor configuration file'' or ''Configuring motor manually'' chapter

== Loading motor configuration file ==
If you have pre-made configuration file made to your motor and SimuCUBE, you may follow this chapter to load it in the IONI and skip the next chapter ''Configuring motor''.
# Click ''Load settings from file''
# Select the file and open it
# Click ''Save settings to drive non-volatile memory'' and answer yes to questions of applying settings and restarting drive afterwards
# All done, proceed to ''Testing settings'' chapter

See also [[List of motors for SimuCUBE]] for pre-made configuration files.

== Configuring motor manually ==
All settings except the one mentioned here should be kept at their factory defaults. If unsure which settings are factory defaults, then repeat firmware upgrade procedure and tick the ''Reset device to factory state'' checkbox before uploading the firmware.

Following settings are constant and always required with SimuCUBE:

|Granite Devices SimuCUBE systems are have one of these ratings: 320W, 480W or 720W. Use value from your model. If under voltage faults occur, try reducing this value little bit (like 10-30W).

Motor parameters depend on the attached motor type and specifications. Refer your motor manufacturer's data sheet to get the correct values in the following fields:

|Machine
|{{Param|MT}}

|{{Param|MPC}}
|8
|8 is a typical value, however 4, 6 are common as well
|-
|Machine
|{{Param|MCC}}
|Maximum motor continuous current 
|Most AC motors specify current as RMS value. Value in this field is entered as [[Peak value of sine]]. To covert RMS current to peak value of sine, multiply it by 1.41.
|-
|Machine
|{{Param|MMC}}
|Motor peak current rating
|Most AC motors specify current as RMS value. Value in this field is entered as [[Peak value of sine]]. To covert RMS current to peak value of sine, multiply it by 1.41. 

This defines the maximum torque that system will produce. For safety reasons, it is recommended to set this value to 20% of motor specified value until system operation has been verified.

After all parameters have been set, click ''Apply settings'' and go to Connect tab and click ''Save settings on drive non-volatile memory''. Many parameter changes need restarting of the drive to activate new settings. If unsure, just click ''Restart drive'' and connect again.

== Testing settings ==
To test settings first time, it is advised to change {{Param|CRI}} temporarily to ''Serial only'' to avoid unexpected motion. After changing any parameter (including CRI),click ''Apply settings'' button to activate the change. 

Testing procedure:
# Have Granity connected to drive and go to Testing tab
# Make sure that nothing is blocking motor rotation and motor is rigidly mounted ('''unexpected and strong rotation or vibration might occur''')
# Release E-stop switch to activate the drive
# Motor should start initializing by swinging back and forth with decreasing amplitude and then become in rest without any torque or shaft holding force
# Manually change torque setpoint by clicking ''Increment by TSP1'' several times. This will increase torque command [[Setpoint signal|setpoint]] on each click. Typically motor should definitely rotate when setpoint is increased above value 5000. Observe motor:
## Motor should start rotating after produced torque exceeds static friction. If motor spins, test has passed! Set setpoint to zero and proceed to finalizing settings.
## If motor does not start rotating, check device status and fault registers in the Testing tab and check [[SimuCUBE troubleshooting]]
## If motor starts holding position (becomes stiff to turn) and has "bumps" if forced to turn anyways, then one of following settings need attention:
### FBI - try inverting this checkbox value and try again
### If FBI didn't help, ensure that MPC and FBR are exactly correct values. See [[Determining motor pole count]] if not sure about pole count.

== Finalizing settings ==
To finalize setup, change {{Param|CRI}} to Pulse Width Modulation, Apply and save settings to drive. For additional settings and tuning of force feedback effects feeling, you may adjust additional Granity parameters such as Torque mode effects in Tuning tab (click ''Show advanced settings''). 

{{machine|When CRI is set to anything but Serial setpoint, IONI drive starts following torque command from external inputs. This means that if MMos firmware is loaded into SimuCUBE, it is able to rotate and send torque command. Beware unexpected rotation when changing this setting.}}

After SimuCUBE all settings have been configured and verified to work, you might want to become back to the settings and adjust motor current limits (MMC and MCC) to increase or adjust maximum torque of motor.
