Delta DVP-20PM

5 Applied Instructions and Basic Usage
drive for instance.)
 Diameter of the slave axis: 200 mm
 Gear ratio for the slave axis: 128/4→The number of pulses it takes for the AC servo drive
connected to the master axis to rotate once is 10,000. (Take Delta ASDA-A2 series AC servo
drive for instance.)
 Length of a cutting: 500 mm
 Setting the parameters in the motion control function block T_RotaryCut
 MasterLength: 150 x π = 471→K471
 MasterPulse: Number of pulses it takes for the master axis specified to rotate once/Gear ratio
for the mechanism used to decelerate the master axis specified→10000/0.1=100000→K100000
 SlaveLength: 200 x π = 628→K628
 SlavePulse: K10000
 SynArea: Approximately 1/3 times the number of pulses it takes for the slave axis specified to
rotate once→K3000
 MaterialSize: K500
 AccCurve=K3 (Cycloid)
 Operation of the cam used
 Set the parameters in the motion control function block T_RotaryCut. After M0 is set to ON, the
slave axis specified will mesh with the master axis specified.
 After M10 is set to ON, the master axis will operate, and the motion of the slave axis will follow
the motion of the master axis.
 Upload the cam chart in the DVP-20PM series motion controller used.
Length of a cutting<Length of the blade used: The speed of cutting roller used is the same as
the speed of the feeding roller used in the synchronization zone designed. After the cutting roller
used leaves the synchronization zone, the cutting roller will accelerate.
 Checking the length of a cutting: The length of a cutting is 500 mm. Convert the length of a
cutting into the number of pulses which the master axis sends in a cycle. (A motor unit is used.
500/471x100000=106157.) Check whether the length of the cam curve in the cam chart
uploaded is 106175 pulses. If the length of the cam curve in the cam chart uploaded is 106175
pulses, the parameters in the motion control function block T_RotaryCut are set correctly.
4. Troubleshooting
Error Troubleshooting
The values of input pins in the motion control function
block are incorrect.
Check whether the values of the input pins are in the
ranges allowed.
A cam curve can not be created.
Check whether the values of the parameters in the
motion control block can be used to create a cam
curve.
