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 SM010S 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 SM010S 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 SM010S 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 SM010S 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 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 DC Drives?
A Data Fault in AC Tech DC Drives means that user data and OEM defaults in the EPM are corrupted.
Hazards of live parts, sensitive components, and need for qualified personnel.
Details input voltage ranges and tolerances for different series.
Specifies required circuit breakers or fuses for safe operation.
Provides required wire gauges (AWG, mm²) for different models.
Guidelines for connecting input power and output motor wires, avoiding internal contactors.
Drive supports speed references via speed pot, 0-10 VDC, and 4-20 mA signals.
How to select speed references using terminals and parameters.
Calibrates drive for applied input voltage (HIGH/LOW).
Defines how the drive starts (normal, power up, DC brake, flying restart).
Defines how the drive stops (coast, DC brake, ramp).
Selects speed reference source when in standard mode.
Sets maximum allowable output current of the drive.
Drive provides solid-state motor overload protection.
Selects operation mode (user/OEM) and resets parameters to defaults.
