P700 / P701
E003 3.0 Inverter overcurrent I 2 t limit has triggered, e.g. > 1.5 x I
n
for 60s
(please also note P504)
• Avoid continuous overload at FI output
3.1 Overcurrent chopper
I 2 t limit for brake chopper triggered
• Avoid overcurrent in braking resistor
E004 4.0 Overcurrent module Error signal from module (short duration)
• Rectify short-circuit or earthing at FI output
• Use external output choke (motor cable is too long)
E005 5.0 Overvoltage dc-link voltage DC link voltage is too high
• Reduce energy return by means of a braking resistor
• Extend deceleration (P103)
• If necessary, set disconnection mode (P108) with
delay (not for lifting equipment)
• Extend quick stop time (P426)
5.1 Overvoltage mains Mains voltage is too high
• Please check 380V-20% ... 480V+10%
or 200 ... 240V
± 10%
E006 6.0 DC-Link voltage undervoltage
(charging error)
Inverter mains/link voltage too low
• Check mains voltage 380V-20% ... 480V+10%
or 200 ... 240V
± 10%
6.1 Mains undervoltage
E007 7.0 Mains phase failure One of the three mains input phases was or is interrupted.
• Check mains phases 380V-20% ... 480V+10%
or 200 ... 240V
± 10%, possibly too low?
• All three mains phases must be symmetrical.
OFF NOTE: OFF appears in the display when the three mains phases are uniformly reduced,
i.e. when a normal mains switch off occurs during operation.
