WARNING

CODE

DESCRIPTION

RECOMMENDED ACTIONS

L Leakage Low

59

Indicates that the Autotune Ls (P220)
measured was less than 0.15 pu.

– REFER TO THE POWERFLEX 7000

SERIES B MANUAL (CHAPTER 4 –
COMMISSIONING) ON AUTOTUNE

PROCEDURES, RESULTS, AND
ACTIONS

L Leakage High

60

Indicates that the Autotune Ls (P220)
measured was greater than 0.30 pu.

L Magnetize Low

61

Indicates that the Autotune L mag (P221)
measured was less than 2.00 pu, and L
magnetizing (P131) will have to be tuned

manually.

L Magnetize High

62

Indicates that the Autotune L mag (P221)

measured was greater than 10.00 pu, and L
magnetizing (P131) will have to be tuned
manually.

Line Cap Range

124

In PWM rectifier drives, the calculated per

unit value of the Line Filter Capacitor
(P133), based on the values entered for
Line Capacitor kVAR (P15), Line Capacitor
Volts (P16), and Line Capacitor Frequency

(P32) is outside of the normal range of 0.35-
0.55pu.

– Verify capacitor nameplate data and

compare with information entered in
drive

Line DC Link OV

116

The measured Line DC voltage has

exceeded Line DC Overvoltage Trip (P173),
and instantaneously causes a warning.

– See associated Fault Description

Line Loss

120

The drive has detected a loss of input

voltage from losing the frequency (PLL) lock
on the input voltage. This is designed to be
a faster method of detecting an
undervoltage. The drive responds to this
warning as it does to a Master UV warning.

– Verify the VSB connections and tap

settings, and check resistance of VSB
board – Megger board to confirm

integrity

– Check TSN fusing
– Check actual voltage values on the

Terminal for each bridge and the total
line voltage

– Check for possible source voltage

supply problems

Liq IO Config

(C-Frame Only)

131

The XIO card which was being assigned to
the Liquid Cooling System Faults Input is
not a card which can be used for this
purpose

– Select the proper slot containing the XIO

card which is compatible for Liquid
Cooling System Faults usage.

Liq IO Conflict

(C-Frame Only)

132

The XIO card previously being used for
Liquid Cooling System Faults has been
reassigned for another purpose.

– Check the configuration of all XIO slots

and reassign if necessary.

Logx IO Config

133

The XIO card which was being assigned to
Logix IO (basic PLC functionality) is not a
card which can be used for this purpose

– Select the proper slot containing the XIO

card which is compatible for Logix IO
usage.

Logx IO Conflict

134

The XIO card previously being used for

Logix IO (basic PLC functionality) has been
reassigned for another purpose.

– Check the configuration of all XIO slots

and reassign if necessary.
