Starting up the inverter with INTERBUS (MCH42A)
The parameters of the MOVIDRIVE
®
compact
MCH42A inverter can be set straight
away via INTERBUS without any further settings once the INTERBUS interface has
been installed. For example, all parameters can be set by the master programmable
controller after power-on.
To do this, control source and setpoint source must be set to FIELDBUS in the inverter
(P100 = FIELDBUS and P101 = FIELDBUS). The FIELDBUS setting means the inverter
parameters are set for control and setpoint entry via INTERBUS. The inverter then
responds to the process output data sent by the master programmable controller.
Activation of the control signal source/setpoint source FIELDBUS is signaled to the high-
er-level controller using the "Fieldbus mode active" bit in the status word. For safety
reasons, you must also enable the inverter at the terminals for control via the fieldbus
system. Consequently, you must wire or program the terminals in such a way that the
inverter is enabled via the input terminals.
The simplest way of enabling the inverter on the terminal side is to set the DIØØ
(/CONTROLLER INHIBIT) input terminal to a "1" signal and to program the input
terminals DIØ1 ... DIØ3 to "NO FUNCTION."
Preliminary work
for startup
1. Enable the inverter at the terminals. To do so, set a "1" signal at X11:1 (DIØØ
"/CONTROLLER INHIBIT"), for example using a jumper to X11:8 (VO24).
2. Only switch on the DC 24 V voltage supply; do not switch on the supply voltage yet.
You can now set the inverter parameters without the motor starting up
unintentionally.
3. Set the control source and setpoint source to FIELDBUS on (P100 = FIELDBUS and
P101 = FIELDBUS).
4. Set binary inputs DIØ1 to DIØ3 to "No function" (P600 to P602 = "No function").
