Control signals
SV
External potentiometer speed regulation
EN
If EN and GNDE connect, the motor runs;
If EN and GNDE disconnect, the motor stops. (They disconnect
by default.)
F/R
If F/ and GNDE connect, the motor runs anti-clockwise
If F/ and GNDE disconnect, the motor runs clockwise
GNDE
Control signal common ground port
BRK
Under port control mode P-03-4, BRK connects with GNDE, the
motor brake stops
Output signals
SPD
Frequency output.
The relationship between the frequency detected and the speed is:
N(rpm)= F
F: Output pulse frequency(Hz） N: Motor speed
For example：F=500Hz, then N(rpm)=500
(Note: Motor poles should be set right)
ALM
It is a high resistance output, and when a fault occurs, it outputs a
low level
