Calculate the values needed for velocity and acceleration (constant values valid for
MAC400, MAC1500 and MAC4500).
1. Set the needed velocity
. V_SOLL = V x 2.8369 [rpm]
Ex.
We need the motor to run with a constant speed of 1200 RPM. So,
V_SOLL = 1200 x 2,8369 = 3404 cnt/smp (= 0x0D4C)
2. Set the needed acceleration
. A_SOLL = A / 271 [RPM/s
2
]
Ex.
We need the motor to accelerate with 100,000 RPM/s
2
so,
A_SOLL = 100,000/271 = 369 cnt/smp
2
(= 0x0171)
Insert the calculated values in send frames and send to motor as shown below (modbus
address 10-11 = register 5, modbus address 12-13 = register 6). Remember to press
the send button for every new value.
Now set the motor in velocity mode and thereby activate the motor.
Ex.
The motor needs to be activated by setting it into velocity mode, so we need to set the
mode register to the value 1. Mode = 1 which is velocity mode, now the motor will use the
acceleration and the velocity just configured.
(Modbus address 4-5 = register 2).
