VLT AutomationDrive FC 301/302
Programming Guide
This parameter cannot be adjusted while the motor is running.
Set digital input to [0] PNP - Active at 24 V in parameter 5-00 Digital I/O Mode.
When using VLT® PTC Thermistor Card MCB 112 always always select [0] None.
Select the input to which the thermistor (PTC sensor) should be connected. An analog input option [1] Analog Input 53 or [2] Analog
Input 54 cannot be selected if the analog input is already in use as a reference source (selected in parameter 3-15 Reference Resource
1, parameter 3-16 Reference Resource 2, or parameter 3-17 Reference Resource 3).

Parameter 1-94 ATEX ETR Cur. Lim. Speed Reduction
Table 139: Parameter 1-94 ATEX ETR Cur. Lim. Speed Reduction
1-94 ATEX ETR Cur. Lim. Speed Reduction
Default value: 0%
Conversion index: -1
Only visible if parameter 1-90 Motor Thermal Protection is set to [20] ATEX ETR.
Configure the reaction for operating in Ex-e current limit. 0%: The drive does not change anything besides issuing warning 163, ATEX
ETR cur.lim.warning. >0%: The drive issues warning 163, ATEX ETR cur.lim.warning and reduces motor speed following ramp 2 (param-
eter group 3-5* Ramp 2).
Example:
Actual reference = 50 RPM
Parameter 1-94 ATEX ETR cur.lim. speed reduction = 20%
Resulting reference = 40 RPM
