Cause
Initial use
Encoder without
multiturn absolute
function used
Low battery power
Battery has no power or
has been dismantled
Display: "Er 151"
1 Content: Encoder communication error
Diagnosis
Verify if encoder cable has
shielding layer
Verify if encoder wiring is correct
Display: "Er 152"
Content: Encoder initial position error
Diagnosis
1. Verify if encoder power supply
voltage is DC5V ± 5% ;
2. Verify if encoder cable and shielded
layer is not damaged;
3. Verify if encoder cable is close to
high-powered power supply cable

Diagnosis
Origin calibration not
performed
Verify if encoder has
multiturn absolute
function
Replace battery and
restart driver to clear
alarm

Solution
Replace with standard encoder
cable
Reconnect encoder wiring
/ Replace motor
Solution
1. Make sure encoder power supply
voltage is stable
2. Make sure encoder cable is not
damaged.
3. Make sure encoder cable shielded
layer is grounded to frame
4. Make sure encoder cable is away
from high-powered power supply
cable
Replace motor
Replace driver
Solution
Perform origin positioning and multiturn
position initialization, calibrate the origin of
coordinate system.
1. Replace the motor with a multiturn
absolute encoder.
2. Set Pr0.15 = 0 to deactivate multiturn
absolute function.
Replace battery
Absolute position lost. Return to origin and
perform multiturn initialization, calibrate the
origin of coordinate system
