Étape 1 - Gather Information - Gear Box

Check Axis.mul and look at the line

SR,7,1,1,291833.500,1,200,500,500,125.1,90.0,InF_SRHome,3,20,5,0.0,5.0,10.0,0.000,

Gear ratio

291833.500   100:1

145602.000   50:1

Étape 2 - Gather Information - Drive used

AX8206 Drive

or

AX5003 Drive

Étape 3 - Gather Information - Motor Being used

It should be a AM8032-E

The AM8032-E has torque constant of 0.8 N/A

...If not seek advice

Étape 4 - Aim

We are aiming to deliver a torque of no more than 56 Nm

For

100:1 the motors maximum delivered torque 0.56 Nm

or

50:1  the motors maximum delivered torque 1.12 Nm

Étape 5 - Regenerate Projects

1. Put old projects into a clearly named folder
2. Create a new empty folder with the name of the machine.
3. Open Project "From Target" to the new folder
4. Check the mappings are present
5. Add a Drive Manager project

Étape 6 - For a AX5003 Drive

Use drive manager to get to the parameters.

Check the value of P-0-092 this value should be 5.9A (if not seek help)

Change the value of S-0-0092 to

12% for 100:1 

or

24% for 50:1

If you have an old drive manager you may have to enter:

The value may be in .1 scale hence factor of 10 and also could be in HEX

120  or 0C00,

240 or  F000  

Étape 7 - For AX8206 Drive

Check channel B 0x3643:1  s/b 2.95A

Change 0x6872 to

24% for 100:1

or

48% for 50:1

Étape 8 - For Both Drives

1. Add to startup parameters
2. Download to drive
3. Save project
4. Activate
5. Update control board

Étape 9 - Crib Table example
