4.5 Alarm Signals (A)

The alarm signals will be shown on the seven segment display of the control board SDCS-CON-x as codes A . . as well as on the LCD of the control panel CDP 31x as plain text. Alarm signals will only be displayed, if there is no fault signal active.

The alarm signals - with the exception of A 101 and A 102 - will not result in switching off the signal 10910 resp. in stopping the drive.

A 101				Start inhibition		Alarm Start Inhibition	11104		bit 0
						Pin 908 (START_INHIBIT) is set to logical
						"1“; drive cannot be switched ON.
						When pin is set to logical "0“, the alarm sig-
						nal will be reset.

A 102				Emergency stop		Alarm EMERGENCY STOP	11104		bit 1
						Pin 906 has a logical "0" level; for signal re-
						set, see introductory remarks in Chapter 4.4
						"Fault Signals“ and Chapter 3.7 "EMER-
						GENCY STOP RESETTING“.

A 103			Motor 1 temp. alarm			Alarm Overtemperature MOTOR 1	11104		bit 2
						Check: - Parameter setting MOT1.TEMP_
						ALARM_L [P 1402] correct?
						See also Fault Code F 6.

A 104			Motor 1 overl.alarm			Alarm Overload MOTOR 1 (Thermal Model 1)	11104		bit 3
						Check: - See Fault Code F 7.

A 105				Conv. overtemp.		Alarm Overtemperature Power Section	11104		bit 4
				alarm		This signal will already appear at approx.
						10 °C below the shutdown temperature ap-
						plying for Fault Signal F 4 (see P 10512).
						Check: - See Fault Code F 4.

A 106			Current reg blocked			Alarm Current Regulator/Controller blocked	11104		bit 5
						Pin 404 (BLOCK) is set to logical "1“.
						When pin is set to logical "0“, the alarm sig-
						nal will be reset.
