GE IC698CPE040-FJ Gas turbine electrical module

Drive-Side Error Reaction The reaction of the drive to detected errors has been expanded as follows: • Via parameter P-0-0119, Best possible deceleration the reaction of the drive to non-fatal and interface errors can be set. In addition to the reactions "Velocity command to zero" and "Torque to zero", "Velocity to zero with ramp and filter" and "Jerk limit" are also used. 

• "NC reaction with error". If a non-fatal error occurs, then the drive error reaction can be delayed by 30 seconds. Seting in parameter P-0-0117, NC reaction on error.

 • In parameter P-0-0118, Power off on error settings can be made for a) the time that power should be switched on, b) shutdown of power with fault, c) execution of a package reaction and d) reaction of the drive to DC bus undervoltage

Monitoring Amplifier Overload

 The thermal load of the controller endstage is performed with a temperature model. The thermal load is displayed in parameter P-0-0141, Thermal drive load. It is no longer necessary to make a setting in a parameter. If the drive limits the effective peak current because of the amplifier overload, then warning E257 Continuous current limit active is generated and bit 0 (overload warning) is set in S-0-0012, Class 2 diagnostics

Monitoring Motor Overload

 For 400msec the fourfold motor standstill current is allowed. The 2.2 fold is continuously allowed. If the motor overload limit is active, then warning E225 Motor overload is generated and bit 0 (overload warning) is set in S-0-0012, Class 2 diagnostics.
