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%
Parameter type: Range, 0 - 100%
Setup: 2 setups
Conversion index: -1
Data type: Uint16
Change during operation: True
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

1-95 Thermistor Sensor Type
Default value: [0] KTY Sensor 1
Parameter type: Option
Setup: All setups
Conversion index: –
Data type: Uint8
Change during operation: True
Select the used type of thermistor sensor.
