What Er1 means

Memory error p. 92

Common causes

  • Power supply turned off while drive was writing data (especially initializing data), and residual control circuit voltage was not high enough to enable writing of data. p. 92
  • High intensity noise was applied to the drive while data (especially initializing data) was being written. p. 92
  • The CPU did not operate normally. p. 92

What to do

  1. CHECK Check whether pressing the key resets the alarm after the function code data are initialized by setting the data for function code H03 to 1. SUGGESTED ACTIONS – Return the initialized function code data to their previous settings, then restart the operation. p. 92
  2. CHECK Check if appropriate noise control measures have been implemented (e.g. correct grounding and routing of control and main circuit wires). Alternatively, perform the same check as described in (1) above. SUGGESTED ACTIONS – Improve noise control. Alternatively, return the initialized function code data to their previous settings, then restart the operation. p. 92
  3. CHECK Initialize the function code data by setting H03 to 1, then reset the alarm by pressing the key and check that the alarm is triggered. SUGGESTED ACTIONS – Replace malfunctioning printed circuit board (PCB). p. 92
