Why am I getting a High DC Bus Voltage Fault on my AC Tech DC Drives?
A high DC bus voltage fault in AC Tech DC Drives can occur due to several reasons: the line voltage might be too high, the deceleration rate might be too fast, or there could be an overhauling load. For fast deceleration or overhauling loads, dynamic braking may be required.
What to do if AC Tech DC Drives show Incompatibility Fault?
If you're encountering an Incompatibility Fault with your AC Tech DC Drives, it means an EPM with an incompatible parameter version has been installed. You can either remove the EPM or perform a factory reset using Parameter 48 to change the parameter version of the EPM to match that of the drive.
How to resolve Control Fault on AC Tech DC Drives?
A Control Fault in AC Tech DC Drives means that a blank EPM or an EPM with corrupted data has been installed. To resolve this, perform a factory reset using Parameter 48 - PROGRAM SELECTION.
What does External Fault mean on AC Tech SM410 DC Drives?
An External Fault in AC Tech DC Drives is triggered when one of the TB-13 terminals is set as an External Fault input and that terminal is open with respect to TB-11. Refer to Parameters 10, 11, and 12.
Why AC Tech SM410 show Start Fault?
A Start Fault in AC Tech DC Drives occurs when a start command was present when the drive was powered up. If START METHOD is set to NORMAL, you must wait 2 seconds after power-up to apply the Start command.
What causes Low DC Bus Voltage Fault in AC Tech SM410 DC Drives?
A Low DC Bus Voltage Fault in AC Tech DC Drives indicates that the line voltage is too low.
What does Dynamic Braking Fault mean in AC Tech DC Drives?
A Dynamic Braking Fault in AC Tech DC Drives means that the drive has detected that the dynamic braking resistors are overheating.
What does Data Fault mean in AC Tech SM410 DC Drives?
A Data Fault in AC Tech DC Drives means that user data and OEM defaults in the EPM are corrupted.
Explains the meaning of signal words (DANGER, WARNING, STOP, Note) and associated icons for safety.
Specifies voltage ratings and operating ranges for various series drives.
Provides tables for input fuse and circuit breaker ratings according to NEC and local codes.
Lists recommended AWG and mm² sizes for input wiring based on drive model and voltage.
Explains how to connect input power and output motor wires, and cautions against inter-drive components.
Covers wiring separation, terminal common, surge suppression, start/stop, and speed references.
Calibrates the drive for the applied input voltage (HIGH or LOW).
Sets the switching rate of output IGBTs to control motor noise and derating.
Configures how the drive starts, including normal, power-up, and flying restarts.
Defines how the drive stops the motor: Coast, Coast with DC Brake, or Ramp to Stop.
Selects the speed reference source when in STANDARD speed mode (keypad, VDC, mA).
Selects operating mode (User/OEM) and resets parameters to factory defaults.
Lists fault codes (AF, CF, dF, etc.) with their descriptions and possible causes.
