EM - 30 Electronic Modules Ver. 0002
EM.4.3 CONNECTOR X2, CONTROL
Modular drive:
When the control circuit is supplied with 24 Vdc (pins 7 and 8) the drive runs an internal test. If
the system is OK, it closes the module status contacts (pins 4 and 5 "Drive OK). This contact
stays closed while the drive is supplied with 24 Vdc and it runs properly. To govern a motor,
the drives also needs energy at the Power Bus.
The maximum internal consumption of the 24 Vdc supply input is 2 Amp for the bigger
Drives. The internal circuits are protected by a 2.5Amp fuse.
See the characteristics table of the previous sections.
With the “Drive Enable” and “Speed Enable” inputs (pins 2 and 3) together with the velocity
command, it is possible to govern the motor. The consumption of these control signals is
between 4.5 and 7 mA. A later graph shows the behavior of the Drive depending on the “Drive
Enable” and “Speed Enable” inputs
