MP2220.x Monitoring functions
Input: Bit 2 – Power limit of spindle at ERR.IZ.GR (only for
HEIDENHAIN inverters, except UE 2xx)
0: Power limit active
1: Power limit inactive
MP2392.x Power limit
Input: 0: No power limiting
0.001 to 3000.000 [kW]
MP2396.x Maximum torque
Input: 0: No torque limiting
0.1 to 30 000.0 [Nm]
MP2223.x Special controller functions
Input: Bit 1 – If a torque is specified via PLC Modules 9128/9158 and
MP2223 bit 1 is set, the NC automatically considers the holding
current in MP2630 when limiting the current. This makes it
possible to use the PLC modules to set a limit value that is
below the holding torque.
0 = Inactive
1 = Consider MP2630 with PLC Modules 9128/9158
Power limiting of the spindle after PLC request
An additional maximum drive power rating can be defined with the machine
parameter MP2393.x. This function must be activated via PLC Module 9314.
This makes it possible to reduce power consumption for starting up the
spindle. This can prevent the maximum power of the power supply module
from being exceeded if an axis is positioned at the same time as the spindle
is started.
The PLC knows (via M3/M4/M5) when the spindle is being started up and
when the defined spindle speed has been reached. During the PLC positioning
movements (tool change) you can switch to the power in MP2393. During
machining (low power consumption of the axes, low traversing speeds) you
can switch to the maximum spindle power (in MP2393, or no power limit).
