16-37 Inv. Max. Current
Range: Function:
Application
dependent*
[0.01 - 10000.00 A] View the inverter maximum current, which should match the nameplate data on the connected
motor. The data are used for calculation of torque, motor protection, etc.
16-38 SL Controller State
Range: Function:
0 N/A* [0 - 100 N/A] View the state of the event under execution by the SL controller.
16-39 Control Card Temp.
Range: Function:
0 C* [0 - 100 C] View the temperature on the control card, stated in °C.
16-40 Logging Buffer Full
Option: Function:
View whether the logging buffer is full (see parameter group 15-1*). The logging buffer will never
be full when par. 15-13
Logging Mode is set to Log always [0].
[0] * No
[1] Yes
3.16.5 16-43 Timed Actions Status
16-43 Timed Actions Status
View the timed actions mode.
Option: Function:
[0] * Timed Actions Auto
[1] Timed Actions Disabled
[2] Constant On Actions
[3] Constant Off Actions
16-49 Current Fault Source
Range: Function:
0 N/A* [0 - 8 N/A] Value indicates source of current fault, including: short circuit, over current and phase imbalance
(from left): [1-4] Inverter, [5-8] Rectifier, [0] No fault recorded
After a short circuit alarm (imax2) or over current alarm (imax1 or phase imbalance) this will contain the power card number associated with the alarm.
It only holds one number so it will indicate the highest priority power card number (master first). The value will persist on power cycle but if a new alarm
occurs it will be overwritten with the new power card number (even if it a lower priority number). The value will only be cleared when the alarm log is
cleared (i.e. a 3-finger reset would reset the readout to 0).
3.16.6 16-5* Ref. & Feedb.
Parameters for reporting the reference and feedback input.
16-50 External Reference
Range: Function:
0.0 N/A* [-200.0 - 200.0 N/A] View the total reference, the sum of digital, analog, preset, bus and freeze references, plus catch-
up and slow-down.
