The Drive Overheat Fault (OHF) indicates that the heat sink temperature has crossed the temperature threshold. This is the information from the temperature sensor located on the heat sink, near the transistor module. When the Thermal Heat Dissipation (THD) is greater than 118% it trips in OHF. 118% is approximately 100 Deg Centigrade temperature on the heat sink. The main causes for the occurrence of this fault are: 1. Excessive ambient temperature. (Provide proper air cooling of the control roo...

Issue: The motor is running backwards with a forward run command on the drive. Product line: Altivar ATV61 and ATV71 Environment: All models, all serial numbers Cause: The phase rotation is inverted coming out of the drive going to the motor. Resolution: Option 1: To correct the motor rotation swap two motor leads on the drive output terminals. Option 2: Go in the simple start menu 1.1 find output phase rotation change it from ABC to ACB. Refer to the ATV61 and ATV71 programm...

Issue: What does ramp increment mean for the Altivar 61/71? Product Line: Altivar 61, Altivar 71 Environment: All serial numbers Cause: N/A Resolution: Ramp increment is a parameter that will change the resolution of the listed parameters: see below Inr M [Ramp increment] 0.01 - 0.1 - 1 0.1 0.01 [0.01]: Ramp up to 99.99 seconds 0.1 [0.1]: Ramp up to 999.9 seconds 1 [1]: Ramp up to 9,000 s...

Issue: Will the relay output, assigned to No Drive Fault, change states on a fault if Auto restart is set to yes? Product Line: Altivar 61 Altivar 71 ATV61 ATV71 Environment: All Cause: Define the No Drive Fault relay relationship with Auto restart function. Resolution: The relay assigned to No Drive Fault will not change states on a fault, if Auto restart is set to YES, until the max restart time is depleted and the fault still exists.

Depending on the conditions in which the drive is to be used, its installation will require certain precautions and the use of appropriate accessories.
Install the unit vertically:
Avoid placing it close to heating elements
Leave sufficient free space to ensure that the air required for cooling purposes can circulate from the bottom to the top of the unit.
Type A Mounting
Type B Mounting
Type C Mounting
By removing the protective blanking cover from the top of the drive, the degree of protection for the drive becomes IP 20.
The protective blanking cover may vary according to the drive model (refer to the user guide).
The protective blanking cover must be removed from ATV 71P•••N4Z drives when they are mounted in a dust and damp proof enclosure.
To ensure proper air circulation in the drive:
Fit ventilation grilles.
Ensure that there is sufficient ventilation. If there is not, install a forced ventilation unit with a filter. The openings and/or fans must provide a flow rate at least equal to that of the drive fans (refer to the product characteristics).
Use special filters with IP 54 protection.
Remove the blanking cover from the top of the drive.
The drive must be mounted in a dust and damp proof enclosure in certain environmental conditions: dust, corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid, etc.
This enables the drive to be used in an enclosure where the maximum internal temperature reaches 50°C.
All terminals are located at the bottom of the drive. Fit interference suppressors on all inductive circuits near the drive or connected on the same circuit, such as relays, contactors, solenoid valves, fluorescent lighting, etc.

The derating curves for the drive nominal current (In) depend on the temperature, the switching frequency and the mounting type. For intermediate temperatures (e.g. 55°C), interpolate between 2 curves.
Above 50ºC, the drive should be fitted with a control card fan kit.
