Automatic Control Of Drives Power Supply (Hv) - CS-Lab CSMIO/IP-A Manual

4.13.5 Automatic control of drives power supply (HV)

The CSMIO/IP-A controller allows for automatic
control of drives power supply and eventually also
some other devices. This function is set in the
menu „Config  ConfigPlugIns  CSMIO/IP-A
CONFIG". The logic of the output operation, defined
as so called „HV Enable" is very easy. Voltage is
switched on at the moment of Mach program "Re-
set" request and stays "on" till 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-A
Below - an example of output connection, used as „HV Enable".
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-A controller. Re-
sponse time for events that cause the disconnection is less than 1ms.
In this example we used digital output no. 2. Power connection of 0-3 inputs group was shown in "Power
supply" section.
