Siemens SINAMICS PERFECT HARMONY GH180, Function Manual

Page: 374 / 538

Order Code Meaning Description
5 T OL Thermal overload rollback The drive has limited the amount of torque produced to prevent thermal
overload of the input transformer.
6 F WK Field weakening rollback This condition exists when the motor flux is low and the application re‐
quires high torque. This prevents "motor pull-out", an unstable operating
condition of the motor, by decreasing the motor torque until flux is re-
established in the motor.
7 C OL Cell overload rollback A cell current overload model has calculated a thermal overload condition
of the drive cells and the drive has limited the amount of torque allowable.
8 NET1 Network 1 limit Torque limited by network 1 setting.
9 NET2 Network 2 limit Torque limited by network 2 setting.
10 ALIM Analog torque Limit Torque limited by analog input.
11 EALM External analog Limit Drive is in torque limit due to external analog limit when in torque mode.
12 ENLM External network Limit Drive is in torque limit due to external network limit when in torque mode.
13 EMLM External menu Limit Drive is in torque limit due to external menu limit when in torque mode.
14 CIMB Cell imbalance Limit AFE cells in regen limit when the sum of the three phase voltage gains
exceed 3 pu. Each phase voltage gain is equal to the number of installed
cells per phase, divided by the active cells in that phase.
15 RLBK Roll back Appears during acceleration if drive has reached its torque limit setting.
16 RGEN Regeneration During normal deceleration, this message will be displayed when the drive
is operating in regen torque limit.
17 BRKG Dual frequency braking Appears while drive is decelerating with dual frequency braking enabled.
18 OVLT Regen Limit for 6-step Indicates that the six-step regeneration torque limit is in effect. It is set
when the cell voltage gets too high, and serves to reduce the regen torque
limit to limit the energy flow from the output (motor) to the cells to pre‐
vent overvoltaging the cells.
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 profile mode limit Appears if the current limit is due to the current profile limit curve.
24 OTRB Over temperature rollback Occurs when cell OT and / or transformer OT switches are active.
25 TSRB Transformer secondary roll‐
back Occures 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..

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.
