Start-up Procedure
Application 2:
Brushless DC servomotor 2444 S 024 B mounted with an optical encoder HEDS 5500 with 512
pulses per revolution; max. encoder frequency response: 100 kHz; operating range of system
for this application: 340 to 4 500 rpm.
1. The recommended max. speed is calculated as follows: n
max
100 000 •
60 / 512 = 11 719 rpm.
There are no problems since this value is higher than the max. speed of the application (4 500 rpm).
2. Selection of resistor R7: R7 = 16 k; resulting in a max. speed of approx. 7800 rpm
(4000000 / 512 ).
Note:
A resistance value selected between 16 k
Ω
and 33 k
Ω
(max. speed 3 900 rpm)
would allow a better use of the speed range (see chapter 18.8.2. Optimizing R7).
3. The dynamic range of the servo amplifier allows to calculate the min. controllable speed,
i.e.: 7 800 rpm / 40 = 195 rpm; there are no problems since the value is below 340 rpm.
4. The gain value allows to calculate the analog input command for a given speed
(speed command = speed/gain).
Example: For 3 500 rpm the speed command is approx 2.2V (speed command
= 3 500 / (800 000 / 512)).
Current limiter
The current limiter is a protection if the motor stalls or if it is overloaded. Allows also to set up
your specific system without the risk to damage the motor.
1. Remove load from motor or disconnect motor phases;
Note:
At this point of the procedure the current limit is not known, hence to avoid
motor damages during adjustment proceed as described above;
2. Determine the voltage value V
