Monitoring of Mains Phases

Description

If a three-phase drive is missing a mains phase and mains phase monitoring is not correctly set, this can cause overload of the product.

NOTICE
	INOPERABLE EQUIPMENT DUE TO MISSING MAINS PHASE Verify that mains phase monitoring is set to "Automatic Mains Detection" or to "Mains ..." with the correct voltage value if the drive is supplied via the mains phases. Verify that mains phase monitoring is set to "DC bus only ..." with the correct voltage value if the drive is supplied via the DC bus. Failure to follow these instructions can result in equipment damage.

NOTICE

INOPERABLE EQUIPMENT DUE TO MISSING MAINS PHASE

Verify that mains phase monitoring is set to "Automatic Mains Detection" or to "Mains ..." with the correct voltage value if the drive is supplied via the mains phases.
Verify that mains phase monitoring is set to "DC bus only ..." with the correct voltage value if the drive is supplied via the DC bus.

Failure to follow these instructions can result in equipment damage.

NOTE: The mains phases are only monitored in the operating states 5 Switched On, 6 Operation Enabled, 7 Quick Stop Active, and 8 Fault Reaction Active.

The parameter ErrorResp_Flt_AC lets you set the error response to a missing mains phase for three-phase devices.

If the product is supplied via the DC bus, mains phase monitoring must be set to "DC bus only ..." with the correct voltage value.

Mains phase monitoring is set by means of the parameter MON_MainsVolt.

Parameter name HMI menu HMI name	Description	Unit Minimum value Factory setting Maximum value	Data type R/W Persistent Expert	Parameter address via fieldbus
MON_MainsVolt	Detection and monitoring of mains phases. 0 / Automatic Mains Detection: Automatic detection and monitoring of mains voltage 1 / DC-Bus Only (Mains 1~230 V / 3~480 V): DC bus supply only, corresponding to mains voltage 230 V (single-phase) or 480 V (three phases) 2 / DC-Bus Only (Mains 1~115 V / 3~208 V): DC bus supply only, corresponding to mains voltage 115 V (single-phase) or 208 V (three phases) 3 / Mains 1~230 V / 3~480 V: Mains voltage 230 V (single-phase) or 480 V (three phases) 4 / Mains 1~115 V / 3~208 V: Mains voltage 115 V (single-phase) or 208 V (three phases) 5 / Reserved: Reserved Value 0: As soon as mains voltage detected, the device automatically verifies whether the mains voltage is 115 V or 230 V in the case of single-phase devices or 208 V or 400/480 V in the case of three-phase devices. Values 1 … 2: If the device is supplied only via the DC bus, the parameter has to be set to the voltage value corresponding to the mains voltage of the supplying device. There is no mains voltage monitoring. Values 3 … 4: If the mains voltage is not detected properly during start-up, the mains voltage to be used can be selected manually. Type: Unsigned decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 Setting can only be modified if power stage is disabled. Modified settings become active the next time the power stage is enabled.	- 0 0 5	UINT16 R/W per. expert	Modbus 1310 IDN P-0-3005.0.15
