What 3001 means

AIp. 148

Common causes

  • Defines the drive response if the analog input (AI) signal drops below the fault limits and AI is used p. 148

What to do

  1. • as the active reference source (Group 11: REFERENCE SELECT) • as the process or external controllers' feedback or setpoint source (Group 40: PROCESS PID SET 1, Group 41: PROCESS PID SET 2 or Group 42: EXT / TRIM PID) and the corresponding PID controller is active. 3021 AI1 FAULT LIMIT and 3022 AI2 FAULT LIMIT set the fault limits. 0 = NOT SEL – No response. 1 = FAULT – Displays a fault (7, AI1 LOSS or 8, AI2 LOSS) and the drive coasts to stop. 2 = CONST SP 7 – Displays an alarm (2006, AI1 LOSS or 2007, AI2 LOSS) and sets speed using the 1208 CONST SPEED 7. 3 = LAST SPEED – Displays an alarm (2006, AI1 LOSS or 2007, AI2 LOSS) and sets speed using the last operating level. This value is the average speed over the last 10 seconds. WARNING! If you select CONST SP 7 or LAST SPEED, make sure that continued operation is safe when the analog input signal is lost. p. 148
