Designed and built by Allen-Bradley, the 1305 AC drives are variable speed drives and they are designed for ensuring control of 3-phase induction motors. The 1305 AC drives are built to provide immunity to most externally generated interference. The coils of DC energized contactors that are associated with the drives should be suppressed with diodes or similar devices. The Allen-Bradley 1305 AC drives come with power ratings 0.37 to 4 kilowatts at a power rating of 380 to 460 Volts AC. The devices support the use of the RFI filters that are used for controlling the radio-frequency conducted emissions. Note that the manufacturer advises that cabling and installation guidelines be strictly adhered to to prevent the occurrence of EMI noise. However, it is recommended that an RFI filter be used wherever there is a likelihood of sensitive devices or circuits being installed on the same AC power supply.
The ambient operating temperature of the 1305 AC drives is 50 degrees Celsius maximum. Therefore, the users should ensure that the proper temperature is maintained when operating the unit. Otherwise, there is a risk of the drives not achieving optimal performance. During the installation of the drives, proper wiring is essential. There are various cable types that can be used for drive installation. For 1305 AC drive installation, use the unshielded cable, but ensure that it is separated from any nearby sensitive circuits. If there are a lot of sensitive circuits nearby, only use the shielded cable. Ensure that the shield is connected to the drive ground and the motor frame ground. Connections should be made at both ends to ensure minimal external magnetic fields.

Drive ouptut current exceeded the software [Current Limit] and the [Cur Lim Trip En] parameter was enabled. | Check programming of [Curr Lim Trip En] parameter. Check for excess load, improper DC boost setting, DC brake volts set too high or other causes of excess current. |
| Drive → HIM | The check sum read from the HIM's EEPROM does not match the check sum calculated from the EEPROM data. | Repeat operation. Replace HIM. |
| Drive Reset Fault - F22 | May occur on power-up. Caused by having the Start (or Run) Input closed, witht eh Stop input open and [Run On Power Up] = Disabled | Check stop connection located at TB2, terminal 8. |
| EEprom Fault - F32 | EEPROM has invalid data or cannot be programmed to valid data | Check cable connection from main control board to power board. Reset to Default Parameters and Cycle power. |
| Hz Err Fault - F29 |
No valid operating frequency. Possible causes: 1. [Maximum Frequency] is less than [Minimum Freq] 2. Skip frequencies and skip bandwith eliminate all operating frequencies. 3. 4-20mA input signal speed reference has been lost or is out of range and [4-20mA Loss Sel] has "Stop-Fault" selected. |
1. Check [Minimum Freq] and [Maximum Freq] parameters. 2. Check [Skip Freq 1], [Skip Freq 2], [Skip Freq 3] and [Skip Freq Band] parameters. 3. Check for broken wires, loose connections, or transducer loss at 4-20mA input, TB2. |
| Hz Sel Fault - F30 | An unconnected adapter has been selected as the active frequency source. | Connect proper adapter or change active frequency source. |
| HIM→Drive |
Error 1 - Check sum read from the HIM's EEPROM does not match check sum calculated from the EEPROM data. Error 2 - The number of parameters in saved profile does not equal master number. Error 3 - Download was attempted to a different type drive (i.e. 1336 -> 1305). Error 4 - Saved data for parameter not correct for new drive. Error 5 - Drive is running while attempting download |
Repeat operation. Old profile corrupt. Save a new profile. Repeat operation. The last parameter programmed will be displayed on the top line. Verify that all parameters have been programmed. If not, manually program any remaining parameters. Download can only occur with the same type of drive. Capabilities of drive are different than the master drive. Press Enter to continue download. when download is complete, manually program the parameter where the error occured. Stop drive, then re-run download. |
| IPM Current Fault - F44 | The internal power module overcurrent limit has been exceeded. | Inspect for short at the drive output or excessive load conditions on the motor, especially cable capacitance to ground. |
