Abstract
A planing device and a method for activating a planing device, with a mining planer reversibly moveable by means of a planer chain, with at least two chain drives having variable-speed drive motors, with a planer travel measurement system and with a motor control device which, for example by position control, delivers activation parameters for a change in rotational speed of the drive motors for changing the planing speed and which is assigned a control modulewith automatic load compensation regulation between the drive motors. A monitoring module is provided, which, for example by position control, switches off the control module for load compensation regulation or modifies its operating mode and delivers different activation parameters to the drive motors.
