6-10
Causes
3 Input signals (SI6, SI7, SI8, SI9, SI10)
are assigned with undefined number.
4 Output signals (SO1, SO2, SO3) are
assigned with undefined number.
5
Output signals (SO4, SO5, SO6) are
assigned with undefined number.
6
Counter clear function is assigned to a
signal number other than SI7.
7 Command pulse inhibit input function is
assigned to a signal number other than
SI10.
0 The motor has exceeded the motor
working range set to Pr5.14 "Allowable
motor operating range setting" against
the position command input range.
1) Gain is not appropriate.
2) Pr5.14 setup value is low.
0 Data in parameter storage area has been
damaged when reading the data from
1
EEPROM at power-on.
0
Data for writing confirmation to EEPROM
has been damaged when reading the
1
data from EEPROM at power-on.
2
0 Both positive and negative direction drive
prohibition inputs (POT and NOT) have
been turned ON at Pr5.04 "Over-travel
inhibition input setting" =0.
Either positive direction drive prohibition
input or negative direction drive
prohibition input has been turned ON at
Pr5.04=2.
Measures
Allocate correct function to each connector
pin.
1) Check the gain (balance between position
loop gain and speed loop gain) and inertia
ratio.
2) Increase the setup value of Pr5.14. Or,
Set Pr5.14 to 0 to disable the protective
function.
• Set up all parameters again.
• If the error persists, replace the driver (it
may be a failure.) Return the product to the
dealer or manufacturer.
Replace the driver. (it may be a failure).
Return the product to a dealer or
manufacturer.
• Check that there is no error in the switches,
wires and power supply connected to the
positive direction/negative direction drive
prohibition input. Check particularly that
start-up of the power supply for the control
signal (DC12 to 24 V) is not slow.
