These alarm codes relate to Model B Servo Alarms Alarm Code Type Description of Alarm/Fault SV 000 TACHOGENERATER DISCONNECT The tachogenerator is disconnected. SV 001 EXCESS CURRENT IN SERVO The servo motor was overloaded. SV 002 BREAKER (FEED_CTL_UNIT) OFF The breaker for the velocity control ciruit tripped. SV 003 ABNORMAL CURRENT IN SERVO Excessive current was detected in the velocity control circuit. SV 004 EXCESS V TO MOTOR Excessive current was detected in the velocity control circuit.

SV 006 VELOCITY UNIT POWER TOO LOW Low voltage was detected in the velocity control circuit. SV 008 EXCESS ERROR ( STOP) Position deviaton when stopped is larger than the value set in parameter No. 1829 SV 009 EXCESS ERROR (MOVING) Position deviaton when stopped is larger than the value set in parameter No. 1828 SV 0010 EXCESS DRIFT COMPENSATION Drift compensation is excessive ( exceeded 500VELO) SV 011 LSI OVERFLOW The value specified for position deviation compensation is not within the range of -32767 to +32767, or the command value of the D/A converter is not within the range of -8192 to +8192. In general, this alarm occurs to incorrect settings. SV 012 MOTION VALUE OVERFLOW A speed greater than 512,000 pulses per second ( frequency converted into detection units) was specified.

SV 017 ILL POSITION CONTROL LSI A fault occured in the LSI for position control. SV 018 INCORRECT DSCG FREQUENCY A fault was detected in a resolver or inductsyn feedback frequency. SV 019 INCORRECT PULSE CODER PULSE A fault was detected in the feedback pulse from the pulse coder. SV 020 INCORRECT PHASE SHIFT VALUE The resolver or induction phase shift cannot be obtained correctly. SV 021 1-REV PULSE SIGNAL INCORRECT The single revolution signal for the pulse coder went on at an incorrect position SV 022 1-REV PULSE MISSING The single revolution signal for the pulse coder went on at an incorrect position SV 023 SV OVERLOAD A servo motor overloaded SV 024 EXCESS ERROR ALARM 2 Alarm 2 for excess synchronous error was generated. SV 025 V-READY ON (INITIALIZING) During servo control, the speed control ready signal ( VRDY) is on even though it is supposed to be off. SV 026 ILLEGAL AXIS ARRANGEMENT Parameter NO. 1023 for specifying the arrangement of servo axes is set incorrectly. SV 027 ILL DGTL SERVO PARAMETER There is an illegal digital servo parameter.
