Order Code Meaning Description
18 OVLT Regen Limit for 6-step Indicates that the six-step regeneration torque limit is in eect. It is set
when the cell voltage gets too high, and serves to reduce the regen torque
limit to limit the energy ow from the output (motor) to the cells to pre‐
vent cell overvoltage.
19 BYPS Cell bypassed Indicates that one or more cells are in bypass.
20 PRCH Pre-charge One of the pre-charge modes is selected and the drive is pre-charging, or
ready to pre-charge.
21 OLTM Open loop test mode Appears if drive control algorithm is set to open loop test mode.
22 MODE Normal mode display This is the typical display message during normal operation.
23 CURP Current prole mode limit Appears if the current limit is due to the current prole limit curve.
24 OTRB Over temperature rollback Occurs when cell OT and / or transformer OT switches are active.
25 TSRB Transformer secondary
rollback
Occurs when cell power is too high for secondary power ratings.
26 IPIT Input interruption time test
failure
The input interruption time exceeded allowable limits or the function "Test
IP Interruption Time" (7126) has not been executed.
27 NT1R Network1 regen limits Regen limits commanded from Network 1.
28 NT2R Network2 regen limits Regen limits commanded from Network 2.

Order Code Meaning Description
1 NOMV No medium voltage No input line voltage detected.
2 INH CR3 inhibit The CR3 or "drive inhibit" input is asserted.
3 OFF Idle state The drive is ready to run but is in an idle state.
4 MAGN Magnetizing motor state The drive is magnetizing the motor or passing through the magnetizing
drive state.
5 SPIN Spinning load state The drive is trying to detect the speed of the motor in order to synchronize
the drive frequency.
6 UXFR Up transfer state The drive is in the "Up Transfer State" preparing to transfer the motor to the
input line.
7 DXFR Down transfer state The drive is in the "Down Transfer State" preparing to transfer the motor
from the input line to the drive.
8 KYPD Keypad speed demand The drive speed demand source is the keypad.
9 TEST Speed/Torque test The drive is in a speed or torque test mode.
10 LOS Loss of Signal The drive 4 to 20 mA analog input signal has dropped below a predened
setting.
11 NET1 Network 1 Indicates drive is being controlled from Network 1.
12 NET2 Network 2 Indicates drive is being controlled from Network 2.
13 AUTO Automatic mode The SOP ag AutoDisplayMode_O is set true usually to indicate drive is
receiving its speed demand from a source other than the keypad or net‐
work. Typically used with an analog input speed source. This mode is
entirely determined by setting the SOP ag. It does not aect NXG oper‐
ation.
14 HAND Hand mode Appears if the drive is running under normal conditions.
15 BRAK Dynamic Braking Indicates that dynamic braking is enabled.
16 DECL Decelerating (no braking) The drive is decelerating normally.
