PARAMETER DESCRIPTIONS VACON · 341
1209 INPUT SWITCH ACKNOWLEDGEMENT 6 (2.2.7.32)
Use this parameter to select the digital input signal that acknowledges the status of the input
switch.
The input switch is normally a switch fuse unit or main contactor with which the power is fed
to the drive. If the input switch acknowledgement is missing, the drive trips at Input switch
open fault (F64). The parameter is available for NXP drives only.
1210 EXTERNAL BRAKE ACKNOWLEDGEMENT 6 (2.2.7.24)
Use this parameter to select the digital input signal that acknowledges the status of the
external brake.
Connect this digital input signal to an auxiliary contact of the mechanical brake. If the brake
opening command is given, but the contact of the brake feedback signal does not close in
given time, a mechanical brake fault shows (fault code 58). The parameter is available for
NXP drives only.
1213 EMERGENCY STOP 6 (2.2.7.30)
Use this parameter to select the digital input signal that activates the emergency stop
function.
Indication to the drive that the machine has been stopped by the external emergency stop
circuit. Select the digital input to activate the emergency stop input to the drive. When the
digital input is low the drive stops as per the parameter definition of ID1276 Emergency stop
mode and indicates the warning code A63.
The parameter is available for NXP drives only.
1217 ID BIT FREE DO1 6 (P2.3.1.6)
Use this parameter to select the signal that controls the digital output.
The parameter has to be set in format xxxx.yy where xxxx is the ID number of a signal and yy
is the bit number. For example, the value for DO control is 43.06. 43 is the ID number of
Status Word. So the digital output is ON when bit number 06 of Status Word (ID no. 43) i.e.
Run Enable is on.
1218 DC READY PULSE 6 (2.3.3.29)
Use this parameter to select the digital input signal that enables charging of the inverter
drive through an input switch.
Charge DC. Used to charge the inverter drive through an input switch. When the DC link
voltage is above the charging level a 2-second pulse train is generated to close the input
switch. The pulse train is OFF when the input switch acknowledgement goes high. The
parameter is available for NXP drives only.
1239 INCHING REFERENCE 1 6 (2.4.15)
Use this parameter to set the frequency references for the inching function.
