Table 3 — Drive Status Indicator Descriptions
NAME | COLOR | STATE | DESCRIPTION | |
| Green | Flashing | Drive ready but not running, and no faults are present. | |
|
| Steady | Drive running, no faults are present. | |
| Yellow | Flashing | Drive is not running. A type 2 | |
|
|
| drive cannot be started. | |
|
| Steady | Drive is not running, a type 1 alarm condition exists. The drive can be started. | |
STS (Status) | Red | Flashing | A major fault has occurred. Drive cannot be started until fault condition is | |
|
| cleared. | ||
|
| Steady | A | |
| Red/Yellow | Flashing Alternately | A minor fault has occurred. When running, the drive continues to run. System is | |
|
|
| brought to a stop under system control. Fault must be cleared to continue. Use | |
|
|
| parameter 950 [Minor Flt Config] to enable. If not enabled, acts like a major | |
|
|
| fault. | |
| Green/Red | Flashing Alternately | Drive is flash updating. | |
| None (Unlit) | Off | Adapter and/or network is not powered, adapter is not properly connected to | |
|
|
| the network, or adapter needs an IP address. | |
| Red | Flashing | An EtherNet/IP connection has timed out. | |
ENET |
| Steady | Adapter failed the duplicate IP address detection test. | |

| Green | Flashing | Adapter is properly connected but is not communicating with any devices on | |
|
|
| the network. | |
|
| Steady | Adapter is properly connected and communicating on the network. | |
| None (Unlit) | Off | Adapter is not powered or is not transmitting on the network. | |
LINK | Green | Flashing | Adapter is properly connected and transmitting data packets on the network. | |
|
| Steady | Adapter is properly connected but is not transmitting on the network. |
NOTES:
1.A Type 1 alarm indicates that a condition exists. Type 1 alarms are user configurable.
2.A Type 2 alarm indicates that a configuration error exists and the drive cannot be started. Type 2 alarms are not configurable.
VERIFYING THAT DC BUS CAPACITORS ARE DIS- CHARGED — The drive’s DC bus capacitors retain hazard- ous voltages after input power has been disconnected. Perform the following steps before touching any internal components:
1.Turn off and lock out input power. Wait five minutes.
2.Verify that there is no voltage at the drive’s input power terminals.
3.Measure the DC bus potential with a voltmeter while standing on a
4.Once the drive has been serviced, reapply input power.
HIGH TEMPERATURE ALARMS — Coolant flow through the cold plate is controlled by an orifice in the refriger- ant line leaving the cold plate. The orifice looks like one of the
MAIN CONTROL BOARD (MCB) COMPONENTS — Figure 13 shows the drive module with the cover removed. To access the control boards, loosen the screw on the face of the keypad mount and swing the keypad mount upward.
The components on the main control board (MCB) are shown in Fig. 14. Note the location of the terminals labeled MCB I/O. The high pressure switch is wired to these terminals as shown in Fig. 15. In the event of a high condenser pressure alarm, the connections at these terminals should be checked and tightened if necessary.
A typical wiring schematic is shown in Appendix A.
