Product Description

CSH01.3C-PB-ENS-ENS-CCD-L2-S-NN-FW is an advanced control section with Profibus master communication. It is a primary component of Bosch IndraDrive motor controllers. The control section plugs into a power section that provides DC power. Slots on the control section allow installation of hardware modules for added functionality. The CSH01.3C-PB-ENS-ENS-CCD-L2-S-NN-FW control section features a software module that supports safe torque off (STO). It also features two encoder IndraDyn modules and a cross communication module. Safe Torque Off is a safety feature that ensures the quick and controlled shutdown of torque production in motor-driven equipment. STO provides a means to de-energize the motor and prevent it from generating torque, even when the power supply is still active. When triggered, STO initiates a series of actions to bring the motor to a safe and controlled stop. The specific implementation may vary depending on the system.

STO interrupts the power supply to the motor by disabling the output of the motor drive or disconnecting the power source. This ensures that the motor does not receive any electrical power to produce torque. The STO system continuously monitors the motor and verifies that the torque production has ceased. This is done by monitoring feedback signals, such as motor current or position, to ensure that the motor is no longer generating any output. STO offers multiple benefits for operators. It ensures that the motor is quickly and reliably de-energized, reducing the risk of unexpected movement or hazardous situations. It provides an additional layer of safety to protect operators, maintenance personnel, and surrounding equipment. When activated, STO eliminates the need to isolate power sources or mechanically lock the motor to perform maintenance tasks. This simplifies maintenance procedures, reduces downtime, and enhances overall system flexibility.
