Safety Product
Introduction
Information information
Trip
OI.AC Instantaneous input over current detected: peak input current greater than 225%
Check correct regen inductor fitted
Check for short circuit on regen component circuitry
3 Check DC connections: Regen to motoring drive for short circuit
Check line synchronisation status
Reduce the values in current loop gain parameters - Pr 4.13 and Pr 4.14 (closed loop vector and servo modes only)
OIAC.P

Power module over current detected from the module input currents

Check correct regen inductor fitted
Check for short circuit on regen component circuitry
104 Check DC connections: Regen to motoring drive for short circuit
Check line synchronisation status
Reduce the values in current loop gain parameters - Pr 4.13 and Pr 4.14 (closed loop vector and servo modes only)
OIdC.P Power module over current detected from IGBT on state voltage monitoring
Vce IGBT protection activated.
109
Check motor and cable insulation.
O.Ld1 Digital output overload: total current drawn from 24V supply and digital outputs exceeds 200mA
26 Check total load on digital outputs (terminals 24,25,26)and +24V rail (terminal 22)
OV DC bus voltage has exceeded the peak level or the maximum continuous level for 15 seconds
Check nominal AC supply level
Check for supply disturbances which could cause the DC bus to rise – voltage overshoot after supply recovery from a notch induced
by DC drives.

PS

Internal power supply fault

Remove any Solutions Modules and reset
5 Check integrity of interface ribbon cables and connections (size 4,5,6 only)
Hardware fault - return drive to supplier
PS.10V 10V user power supply current greater than 10mA
Check wiring to terminal 4
8
Reduce load on terminal 4
PS.24V

24V internal power supply overload

The total user load of the drive and Solutions Modules has exceeded the internal 24V power supply limit.
The user load consists of the drive's digital outputs plus the SM-I/O Plus digital outputs, or the drive's main encoder supply plus the
SM-Universal Encoder Plus and SM-Encoder Plus encoder supply.

• Reduce load and reset
• Provide an external 24V >50W power supply
• Remove any Solutions Modules and reset
PS.P

Power module power supply fail

Remove any Solutions Modules and reset
108 Check integrity of interface ribbon cables and connections (size 4,5,6 only)
Hardware fault - return drive to supplier
