VLT ® 2900 Series Output current lower than I HIGH par. 224 (below current high) [14] Alarm or warning , the output is activated by an alarm or warning. Feedback higher than FB LOW par. 227 (above feedback low) [15] Current limit , the output current is higher than the value programmed in parameter 221 Current limit I LIM . Feedback lower than FB HIGH par. 228 (under feedback high) [16] Alarm , The output is activated by an alarm. Relay 123 (RELAY 123) [17] Output frequency higher than f LOW , the output frequen- cy is higher than the value set in parameter 225 Warning: Low frequency, f LOW .
Reversing (REVERSE) [18] Thermal warning (THERMAL WARNING) [19] Local operation (LOCAL MODE) [20] Output frequency lower than f HIGH , the output frequen- cy is lower than the value set in parameter 226 Warn- ing: High frequency, f HIGH . Out of frequency range par. 225/226 (out of freq range) [22] Out of current range (out of current range) [23] Output current higher than I LOW , the output current is higher than the value set in parameter 223 Warning: Low current, I LOW . Out of feedback range (out of fdbk. range) [24] Output current lower than I HIGH , the output current is lower than the value set in parameter 224 Warning: High current, I HIGH . Mechanical brake control (Mech.
brake control) [25] Feedback higher than FB LOW , the feedback value is higher than the value set in parameter 227 Warning: Low feedback, FB LOW . Control word bit 11 (control word bit 11) [26] The relay output can be used for giving the present status or warning. The output is activated (1-2 make) when a given condition is fulfilled. Feedback lower than FB HIGH , the feedback value is lower than the value set in parameter 228 Warning: High current, I HIGH . Relay 123 is only used in connection with Profidrive. No function . Is selected if the frequency converter is not to react to signals. Reversing , The relay output is activated when the di- rection of motor rotation is anti-clockwise.
When the direction of motor rotation is clockwise, the value is 0 V DC. Unit ready , there is a supply voltage on the control card of the frequency converter, and the frequency con- verter is ready for operation. Thermal warning , above the temperature limit in either the motor or the frequency converter, or from a ther- mistor connected to a digital input. Enable, no warning , the frequency converter is ready for operation, but no start command has been given. No warning. Local operation, the output is active when in parameter 002 Local/remote operation, Local operation [1] has been selected. Running is active when there is a start command or the output frequency is above 0.1 Hz.
Also active during ramp-down. Out of the frequency range, the output frequency is out of the programmed frequency range in parameters 225 and 226. Running in reference, no warning speed according to reference. Out of the current range, the motor current is out of the programmed range in parameters 223 and 224. Running, no warning , a start command has been given. No warning. Out of the feedback range, the feedback signal is out of the programmed range in parameters 227 and 228. Ready - mains voltage within range , the frequency con- verter is ready for use; the control card is receiving a supply voltage; and there are no active control signals on the inputs.
The mains voltage lies within the voltage limits. Mechanical brake control, enables you to control an external mechanical brake (see section about control of mechanical brake in the VLT 2800 Design Guide). = factory setting, () = display text, [] = value for use in communication via serial communication port 42 MG.29.A3.02 - VLT ® is a registered Danfoss trademark Function: Description of choice:
