PNU Description
P078 Reduction of converter rated supply voltage
i001: Rated input voltage
(G101)
i002: Irrelevant
The rated voltage value of the power system actually used to supply the
power section must be set in this parameter.
This setting acts as the reference for the undervoltage, overvoltage and
phase failure monitoring functions (see also P351, P352 and P353) as well
as for connectors K0285 to K0289, K0291, K0292, K0301, K0302, K0303
and K0305
11.6 Setting values for converter control
P080 Control word for brake control
*
1 The brake is a holding brake
When the "Operating enable" command is cancelled and the
(G140)
"Voltage disconnection" command is input, the "Close brake"
command is not input until n<n min (P370, P371) is reached.
2 The brake is an operating brake
When the "Operating enable" command is cancelled and the
"Voltage disconnection" is input, the "Close brake" command is
input immediately, i.e. while the motor is still rotating.
P083 Selection of actual speed value
*
0 Actual speed value is not yet selected (fixed value 0%)
FDS
1 Actual speed value supplied by "Main actual value" channel
(K0013) (terminals XT.103, XT.104)
(G151)
2 Actual speed value supplied by "Actual speed from pulse
encoder" channel (K0040)
3 Do not set!
4 Actual speed value is wired up freely (selected in P609)
P084 Selection of closed-loop speed / current or torque control
*
1 Operation under closed-loop speed control
2 Operation under closed-loop current / torque control:
(G160)
the setpoint supplied by the ramp-function generator output is
input as a current or torque setpoint (speed controller is
bypassed
P085 Wait period after cancellation of inching command
After an inching command has been cancelled, the drive dwells in operating
state o1.3 for the time period set in this parameter with the controllers
disabled. This wait period does not commence until n<n min (P370, P371) is
reached. If a new inching command is input within this period, then the
drive switches to the next operating state (o1.2 or lower). However, if the
time runs out without a new inching command being entered, then the drive
switches to operating state o7 (see also Section 9).
P086 Voltage failure period for automatic restart
If the voltage fails (F001, F004) at one of the terminals U1, V1, W1, 5U1, or
5W1, or if it drops below a certain threshold (F006 undervoltage) or
exceeds a certain threshold (F007 overvoltage), or its frequency is too low
(F008 frequency < P363) or too high (F009 frequency > P364), then the
corresponding fault message is activated only if the fault condition has not
been eliminated within the "Automatic restart" period set in this parameter.
The gating pulses and controllers are disabled while the fault conditions are
present. The converter waits in operating state o4 or is in o13.
Setting this parameter to 0.00s deactivates the "Automatic restart" function.
NOTE:
Setting values higher than 2.00s are effective only in relation to the voltages
at terminals U1, V1and W1.
A "restart time" of 2.00 s is operative in this case for the voltage at
terminals 5U1 and 5W1 (electronics power supply).
