Option "Lock bFail at TroubleQSP"
The TroubleQSP
device status gets active as soon as a monitoring function responds that has been
parameterised for the "TroubleQSP" error response. Since the bFail status output is not set in this
case, it is not recognisable after pulse inhibit due to e.g. automatic brake operation (as well for a
higher-level control), why the drive is standing und does not start when the setpoint is selected.
Only after an error reset, a setpoint is accepted again.
From version 11.00.00: If the "Lock bFail at TroubleQSP" option is activated (bit 14 = "1") in C00148
,
the bFail status output is also set to TRUE if the device status is TroubleQSP
.
4.4.1 wCANControl/wMCIControl control words
The inverter is controlled by a master control (e.g. IPC) via the wCanControl or wMCIControl control
word, respectively.
• wCANControl: Control word via system bus (CAN)
• The process data word is provided at the wCanControl input via the upstream LP_CanIn1
port
block.
• Display parameter: C00136/2
• wMCIControl: Control word via a plugged-in communication module (e.g. PROFIBUS)
• The process data word is provided at the wMCIControl input via the upstream LP_MciIn1
port
block.
• Display parameter: C00136/1
• The bit assignment for the wCanControl/wMCIControl control words can be seen from the table
below.
