E7 Drive

E7 Drive - YAI

1/2 - 500HP

The E7 Drive was designed exclusively for Commercial HVAC applications. All features were designed for this purpose, including Building Automation communications.

Metasys N2, APOGEE FLN and Modbus were embedded. EtherNet/IP, Modbus TCP/IP and LonWorks were plug-in options. The drive was plenum rated for variable torque applications. Anti-windmilling, motor preheat, energy-savings, and PI setpoint control were standard. Many options were available.

When dealing with harmonic noise, which is better-- an AC or a DC reactor? Posted Date: 06/20/2013 Answer: Use an AC reactor when attaching a reactor to the power supply side, and a DC reactor when attaching to the series + and - bus terminals on the inverter. They are both equally effective. They can also be used in combination. Refer to the attached technical note from a manufacturer of AC chokes and DC reactors for a detailed explanation of solutions to harmonic noise in AC drives.

What will happen if there is only .5'' clearance from either top or bottom of the drive to an enclosure? Posted Date: 03/14/2006 Answer: There MUST be a minimum of 4.7'' clearance above and below the drive (varies by model) to allow airflow over the heat sink. Otherwise, an OH alarm (cooling fin overheat) may occur. Also, a minimum 1.2'' clearance (varies by model) is required on each side of the drive. Refer to the appropriate drives instruction manual for the mounting and clearance specifications.

What is the ambient temperature derating (L8-12 setting)? Posted Date: 01/22/2007 Answer: The output current capacity and the overload capabilities of the inverter depend on the ambient temperature. The higher the ambient temperature the lower is the maximum output current because the heat dissipation becomes more difficult. The overload protection function is active only when the current is above the maximum continuous output current level (112% of inverter rated current). At ambient temperatures higher than 45°C (40°C for IP20) this level will be lowered. The ambient temperature can be set in parameter L8-12. The setting range is 45°C to 60°C. Because the inverter has no IP00/20 detection the set value for L8-12 must be 5° higher than the real ambient temperature at IP20 units.

What are some concerns when the motor cable is over 100 meters? Posted Date: 06/20/2013 Answer: Motor torque will be reduced from a drop in voltage over the cable length. When using lengthy wires with the inverter and the motor, use wires that are thick enough to assist in reducing cable loss. Drive V/f characteristics may need adjusting to compensate for cable losses . The carrier frequency should typically be reduced as follows based on the cable length. up to 50 meters: under 10kHz. Up to 100 meters, under 5 kHz. To tune a custom V/f pattern. see the attached.
