Description
Dissipates the drive surplus braking energy conducted by the brake chopper to
heat
Brake chopper modules under control of one control board, and related accessories
I/O module for controlling cabinet fans
One section of a cabinet-installed drive. A cubicle is typically behind a door of its
own.
DC circuit between rectifier and inverter
Frequency converter for controlling AC motors
Electromagnetic compatibility
Insulated gate bipolar transistor
DC circuit between rectifier and inverter
Converts direct current and voltage to alternating current and voltage.
Drive for controlling several motors which are typically coupled to the same ma-
chinery. Includes one supply unit, and one or several inverter units.
Brake chopper control board
Series of optional, liquid-cooled brake chopper modules
In the drive control program, user-adjustable operation instruction to the drive, or
signal measured or calculated by the drive.
In some (for example fieldbus) contexts, a value that can be accessed as an object,
eg, variable, constant, or signal.
Converts alternating current and voltage to direct current and voltage
Series of brake resistors
