Page 23: Overview
AF-70 LP Macro Configurations 7. Analog and Digital Input Macro Configurations 7.1. Overview AF-70 uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key parameters which determine the input functions and drive behaviour: F-12 – Selects the main drive control source and determines how the output frequency of the drive is primarily controlled. H-15 – Assigns the Macro function to the analog and digital inputs. Additional parameters can then be used to further adapt the settings, e.g. H-16 – Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA H-30 – Determines whether the drive should automatically start following a power on if the Enable Input is present H-31 – When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive. H-47 – Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA The diagrams below provide an overview of the functions of each terminal macro function, and a simplified connection diagram for each. 7.2.

Page 25: Fire Mode
AF-70 LP Macro Configurations 7.7. Fire Mode The Fire Mode function is designed to ensure continuous operation of the drive in emergency conditions until the drive is no longer capable of sustaining operation. The Fire Mode input may be a normally open (Close to Activate Fire Mode) or Normally Closed (Open to Activate Fire Mode) according to the setting of H-30 Index 2. In addition, the input may be momentary or maintained type, selected by H-30 Index 3. This input may be linked to a fire control system to allow maintained operation in emergency conditions, e.g. to clear smoke or maintain air quality within that building. The fire mode function is enabled when H-15 = 15, 16 or 17, with Digital Input 3 assigned to activate fire mode. Fire Mode disables the following protection features in the drive: O-t (Heat-sink Over-Temperature), U-t (Drive Under Temperature), Th-FLt (Faulty Thermistor on Heat-sink), E-trip (External Trip), 4-20 F(4- 20mA fault), Ph-Ib (Phase Imbalance), P-Loss (Input Phase Loss Trip), SC-trp (Communications Loss Trip), I.t-trp (Accumulated overload Trip) The following faults will result in a drive trip, auto reset and restart: O-Volt (Over Voltage on DC Bus), U-Volt (Under Voltage on DC Bus), h O-I (Fast Over-current Trip), O-I (Instantaneous over current on drive output), Out-F (Drive output fault, Output stage trip) 7.8.

AF-7 9.4. Additional Information for UL Compliance AF-70 is designed to meet the UL requirements. For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333 In order to ensure full compliance, the following must be fully observed. Input Power Supply Requirements Supply Voltage 200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum 380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS Imbalance Maximum 3% voltage variation between phase – phase voltages allowed All AF-70 have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have supply imbalance greater than 3%, GE recommends the installation of input line reactors.

Page 29: Trouble Shooting
AF-70 LP Help 10. Trouble Shooting 10.1. Fault Code Messages Fault No. Description Suggested Remedy Code no-Flt No Fault Not required OI-b Brake channel over current Check external brake resistor condition and connection wiring OL-br Brake resistor overload The drive has tripped to prevent damage to the brake resistor O-I Output Over Current Instantaneous Over current on the drive output. Excess load or shock load on the motor. Note: Following a trip, the drive cannot be immediately reset. A delay time is inbuilt, which allows the power components of the drive time to recover to avoid damage. I.t-trp Motor Thermal Overload (I2t) The drive has tripped after delivering >100% of value in F-08 for a period of time to prevent damage to the motor. PS-trp Power stage trip Check for short circuits on the motor and connection cable O-Volt Over voltage on DC bus Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs on deceleration or stopping, increase the deceleration time in F-04 or install a suitable brake resistor and activate the dynamic braking function with H-34 U-Volt Under voltage on DC bus The incoming supply voltage is too low. This trip occurs routinely when power is removed from the drive. - Page 30 AF-7 Notes Intro...
