Code 207432: <location>Drive: Synchronous motor without overvoltage protection

Message value: %1 Drive object: SERVO Reaction: OFF2 (OFF1) Acknowledge: IMMEDIATELY Cause: Under voltage conditions, a synchronous motor c an generate an overvoltage condition that can destroy the drive system. Fault value (r0949, interpret hexadecimal): Associated Drive Data Set (DDS). Remedy: Overvoltage protection can be implemented in the following ways: - limit the maximum speed (p1082) without any additional protection. The maximum speed without protec tion is calculated as follows: Rotary motors: p1082 [rpm] <= 11.695 * p0297/p0316 [Nm/A] Linear motors: p1082 [m/min] <= 73.484 * p0297/p0316 [N/A] - use a voltage protection module (VPM) in conjunct ion with the function "Safe Torque Off" (p9601, p9801). When a fault condition exists, the VPM short-circuits the motors. Duri ng the short-circuit, the pulses must be suppressed - this means that the terminal s for the function "Safe Torque Off" must be connected to the VPM. When using a VPM, p0643 must be set to 1. - activating the internal volt age protection (IVP) with p1231 = 3.
