*ask for help from manufacture.
PP-1
Pressure sensor
fault
*Pressure sensor damaged;
*Pressure sensor oil outlet blocks up;
* Pressure sensor power malfunction;
*The wiring between pressure sensor
and servo drive disconnected.
*FA19 is not set correctly *replace pressure sensor;
*check and dredge oil outlet;
* check if pressure sensor power is normal;
*check the wiring between pressure sensor and servo
drive
*check pressure sensor zero drift.
PP-2

PGo
Protection of
resolver
*Motor feedback Resolver base is not
welded well
*Resolver cable damaged;
* Resolver interface of control board
is damaged.
*check the Resolver base weld.
*replace the Resolver wiring
*ask for help from manufacture.
Tro
KTY84
disconnected
protection
Servo drive can not detect KTY84.
*check the cable.
*check whether resistor detecting temperature is normal.
AL05
Resolver
commutation fault
*Commutation not checked.
* Motor sequence is wrong.
*Pump or motor is locked-rotor, or
motor speed is lower than 5 rpm.
*Please set F822=1 to check commutation.
*Please change the sequence of two phase and check
commutation
*Exclude locked-rotor fault or increase speed to higher
than 5rpm.
