0x2004 Brake Options

This parameter provides options for operating a brake. A brake can be used to fix the motor shaft in a given position, for example for holding up a robot's arm. Since a brake pin is spring-activated when powered off, it must be pulled out by a solenoid to be released. Therefore a release (pull) voltage must be applied to the solenoid to disengage the brake, and after a pre-defined time, a holding voltage is applied to keep the pin retracted.

Hold voltage 0x2004:2 UDINT 32 0 mV readwrite

Voltage required to hold the brake in an open state. This voltage may be set lower than the "Pull voltage" to reduce losses in the brake. CAUTION! Before setting this parameter, contact your brake manufacturer to ensure reliable operation.
