Example: Position Mode (Single motor)

::

from EZMotionMMS2 import *
Motor1= Ezm("COM24", 1, 115200)
Motor1.Shutdown()                  # Shutdown and Enable the motor

# Set modes of operation to Relative Position mode
Motor1.Set_Op_Mode("POSITION REL")

#print selected modes of operation
print(Motor1.Read_Op_Mode())

Motor1.Enable_Motor()

#send new target position (10 turns + 180 degrees in CCW direction) to the motor and update
Motor1.Set_Target_Position(10,180,"CCW")
Motor1.Update()

# wait for the motor to reach target position
while (Motor1.Pos_Target_Check_Flag() == False):
    pass

# Read and print motors current position
turns,angle = Motor1.Read_Actual_Position()
print("Turns = ", turns)
print("Angle = ", angle)

#send new target position to the motor and update
Motor1.Set_Target_Position(5,180,"CW")
Motor1.Update()

# wait for the motor to reach target position
while (Motor1.Pos_Target_Check_Flag() == False):
    pass

Motor1.Disable_Motor()

Example: Speed Mode (Single motor)

::

import time
from EZMotionMMS2 import *
#Create motor object with slave address 1 and port COM24
Motor1= Ezm("COM24", 1, 115200)
Motor1.Shutdown()

# Set modes of operation to Speed mode
Motor1.Set_Op_Mode("SPEED")
Motor1.Shutdown()

Motor1.Set_Acceleration(500)
Motor1.Set_Deceleration(500)

# Set target velocity to 1000rpm in CW direction
Motor1.Set_Target_Velocity(-1000)

Motor1.Enable_Motor()
time.sleep(5)
#read and print motor actual velocity
print("Motor Speed = ", Motor1.Read_Actual_Velocity())

#print selected modes of operation
print(Motor1.Read_Op_Mode())

# Set target velocity to 1000rpm in CCW direction
Motor1.Set_Target_Velocity(1000)

time.sleep(5)
Motor1.Disable_Motor()

Example: Torque Mode (Single motor)

::

from EZMotionMMS2 import *
import time

#Create motor object with slave address 1 and port COM24
Motor1= Ezm("COM24", 1, 115200)

Motor1.Shutdown()

# Set modes of operation to Torque mode
Motor1.Set_Op_Mode("TORQUE")

#Set target motor torque
Motor1.Set_Target_Torque(-80)

Motor1.Enable_Motor()

#read and print actual motor torque
print(Motor1.Read_Actual_Torque())
time.sleep(15)

#read and print motor actual velocity
print("Motor Speed = ", Motor1.Read_Actual_Velocity())

#read and print actual motor torque
print(Motor1.Read_Actual_Torque())

#print selected modes of operation
print(Motor1.Read_Op_Mode())

Motor1.Disable_Motor()

Example: Homing Mode (Single motor)

::

from EZMotionMMS2 import *
import time
Motor1= Ezm( "COM24", 1, 115200)
Motor1.Shutdown()
Motor1.Set_Op_Mode("HOMING")
Motor1.Shutdown()
Motor1.Homing_Method(-3)
Motor1.Homing_Torque(200)
Motor1.Update()


Motor1.Enable_Motor()
time.sleep(5)
print("Motor Speed = ", Motor1.Read_Actual_Velocity())
print(Motor1.Read_Op_Mode())
# Motor1.Set_Target_Velocity(1000)
time.sleep(5)

Motor1.Disable_Motor()

Example: Speed Mode (Dual motor)

::

import time
from EZMotionMMS2 import *
#Create motor object with slave address 1 and port COM?
Motor1= Ezm("COM24", 1, 115200)
#Create 2nd motor object with slave address 2 and port COM?
Motor2= Ezm("COM2", 2, 115200)
Motor1.Shutdown()
Motor2.Shutdown()

# Set modes of operation to Speed mode
Motor1.Set_Op_Mode("SPEED")
Motor1.Shutdown()
Motor2.Set_Op_Mode("SPEED")
Motor2.Shutdown()


Motor1.Set_Acceleration(500)
Motor1.Set_Deceleration(500)

Motor2.Set_Acceleration(500)
Motor2.Set_Deceleration(500)

# Set target velocity to 1000rpm in CW direction
Motor1.Set_Target_Velocity(-1000)

# Set target velocity to 1000rpm in CCW direction for 2nd motor
Motor2.Set_Target_Velocity(1000)

Motor1.Enable_Motor()
Motor2.Enable_Motor()
time.sleep(5)
#read and print motor actual velocity
print("Motor Speed = ", Motor1.Read_Actual_Velocity())
print("Motor Speed = ", Motor2.Read_Actual_Velocity())

#print selected modes of operation
print(Motor1.Read_Op_Mode())
