www.controltechniques.com Issue Number: 2
OI.AC
Instantaneous input over current detected: peak input current greater than 225%
3
Check correct regen inductor fitted
Check for short circuit on regen component circuitry
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
104

(closed loop vector and servo modes only)
OIdC.P
Power module over current detected from IGBT on state voltage monitoring
109
Vce IGBT protection activated.
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
2
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.
Drive voltage rating Peak voltage [0V] Maximum continuous voltage level

PAd
Keypad has been removed when the drive is receiving the speed reference from the keypad
34
Fit keypad and reset
Change speed reference selector to select speed reference from another source
PS
Internal power supply fault
5
Remove any Solutions Modules and reset
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
8
Check wiring to terminal 4
Reduce load on terminal 4
PS.24V
24V internal power supply overload
9
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

•
Remove any Solutions Modules and reset
PS.P
Power module power supply fail
108
Remove any Solutions Modules and reset
Check integrity of interface ribbon cables and connections (size 4,5,6 only)
Hardware fault - return drive to supplier
SCL
Drive RS485 serial comms loss to remote keypad
30
Refit the cable between the drive and keypad
Check cable for damage
Replace cable
Replace keypad
