Panasonic MINAS S Series Operating Manual page 90

The motor does not rotate.
Category
Parameters The control mode selected is not
correct.
The torque limit has been set to 0. Check the value of Pr5E (torque limit set-up). Change
The zero speed clamp is ON, so
the motor does not operate.
Internal velocity set-up parameter
is not entered.
Wiring T h e c i r c u i t f o r C W / C C W
overtravel inhibit is open.
CN I/F Servo-ON signal is not
received.
CN I/F counter clear is ON
(shorted).
Installation Motor lock
Parameter values change to the former value.
Category
Parameter Parameter
downloaded into EEPROM before
power off.
Causes
Check the value of Pr02 (control mode set-up).
0: position control, 1: internal velocity control,
the value to 300 (default).
Check the value of Pr06 (ZERPSPD input selection).
Change the value to 0. If the value is 1, the zero clamp
function is valid. If you desire to set the parameter to 1,
enable the zero speed clamp input, and adjust the
wiring so that the zero speed clamp input can be turned
on correctly.
Check the values of Pr53 through Pr56.
Set a desirable number of revolution.
Check the value of Pr04. If the value is 0, connect
between CN I/F pins 8 and 13, and 7 and 13.
Connect (short circuit) between CN I/F pins 2 and 1 3 .
Disconnect between CN I/F pins 4 and 13.
Turn off the power. Disconnect the motor. Rotate the
motor shaft by hand to make sure that the motor rotates
freely. If the motor is fitted with an electromagnetic brake,
rotate the shaft by hand while applying a voltage
(24VDC) to the brake. If the motor does not rotate,
consult the sales agent to repair it.
Causes
values are not See "Parameter Setting" chapter.
