E-22
For example ：
If there is a hardware Quick stop function,
A. Connect the Quick stop signal
B. Set Index 0x6040 = 0x7E
C. Set Index 0x6040 = 0x7F, now the drive status is operating.
D. Set Index 0x6042 = 1500 (rpm), the default pole number is 4,frequency is
1500(120/4)=50Hz ， and pole settings is on 5-04(1
st
motor) 、 5-16(2
nd
motor).
Motor speed formula
：
p
120
f n
 
rpm=(120*frequency)/pole n
：
rotation speed (rpm) (rounds/minute)
p
：
motor’s pole number (Pole)
f
：
rotation frequency (Hz)
Example 1
：
Set forward 30 Hz, pole number is 4 (120*30)/4 = 900rpm
Example 2
：
Set reverse 20 Hz, pole number is 6 (120*15)/6 = 300rpm
And 300 = 0x012C the plus or minus sign is defining as bit15
So that Index 6042 = -300 = (300’ + 1) = 0x012C ’ + 1 = 1 = 0xFED4
