Automatic control of drives power supply (HV)
The CSMIO/IP-S controller allows for automatic control of drives power supply and eventually some
other devices. Switching on this function was described in Chapter 10th. The logic of the output op-
eration, defined as so-called „HV Enable” is very easy. Voltage is enabled at the moment of Mach
program “Reset” request and stays “on” until one of the following conditions exist:
•
FAULT signal from any axis drive
•
E-Stop signal (the emergency stop mushroom pressed)
•
Limit switch activation
•
Loss of communication with the Mach3 program
•
Error of position/speed regulators inside the CSMIO/IP-S
Here is an example of connected outputs used as „HV Enable”. The output number is irrelevant, it is
defined in the configuration window of the Mach3 program.
When you use large contactors for switching off the power, check if the coil doesn’t take more than
250mA. If so, use smaller transmitter and turn on the bigger one with it. With a large contactor it’s
good to have a diode and noise-suppression condenser to eliminate the overvoltages generated
during switching off the coil.
The „HV Enable” voltage control function is performed automatically by the CSMIO/IP-S controller.
Response time for events that cause the disconnection is less than 1ms.
