Operating Functions
• If the positioning loop gain is small and the setting of this parameter is too small, a deviation
counter overflow (alarm code 24) may be detected even during normal operation.
• Deviation counter overflow (alarm code 24) will not be detected if this parameter is set to 0.
• Use this parameter to set the overflow level for Speed Command Input (REF: CN1 pin 14) or
Torque Command Input (TREF1: CN1 pin 14) using voltage after offset adjustment.
• Excessive analog input (alarm code 39) will not be detected if this parameter is set to 0.
• Use this parameter to set the overload detection level.
• The overload detection level will be 115% if this parameter is set to 0.
• This parameter should normally be set to 0. The setting should be changed only when it is
necessary to reduce the overload detection level.
• The setting of this parameter is limited to 115% of the Servomotor rating.
• Use this parameter to set the overspeed detection level.
• The overspeed detection level will be 1.2 times the maximum Servomotor rotation speed if this
parameter is set to 0.
• This parameter should normally be set to 0. The setting should be changed only when it is
necessary to reduce the overspeed detection level.
• The setting of this parameter is limited to 1.2 times the maximum Servomotor rotation speed.
• The detection margin of error for the setting is
±3 r/min for a 7-core absolute encoder and
±36 r/min for a 5-core incremental encoder.
