Model A64295, Soft-Start with Speed Selection
Setable Ramp Time: 1 to 60 seconds.
Target-Speeds can be set: below base speed - at base speed - above base speed.
Target-Speed Control Options:
The target-speed input read at startup is followed. The target-speed cannot be changed during operation.
Stopping: The motor will coast to a stop when the target-speed input is switched off.
Model A64295/OV, Soft-Start with Variable Speed & Overhauling Braking
Setable Ramp Time: 1 to 60 seconds.
Target-Speeds can be set: below base speed - at base speed - above base speed.
Target-Speed Control Options:
The target-speed can be changed during operation.
A voltage dump IGBT is installed to dump braking energy into an external resistor. This feature allows:
Stopping: The motor will coast to a stop from base speed when the target-speed input is switched off.
Maximum dump current: 100 amps -- Recommended dump resistor value: 4 ohms.
Part A62499, Hand-Held Data Terminal
The data terminal is used to customize performance. The terminal menus provide rapid access for setting and checking operating parameters, status, faults and diagnostics.
Part A63893-16V, Optional Remote-Mount Operator Display
4X20 LCD display reports operating conditions and fault status. Order required cable A62811-2.10.
Optional Velocity Readout
A velocity encoder input is standard; with an optional user-installed encoder connected, the motor speed can be displayed.Order Writing Data
