INDICATION
(DISPLAY) FAILURE INDICATION ITEM DESCRIPTION
EF Simultaneous forward and Fwd Run and Rev Run commands are both closed for
(blinking) reverse operation commands more than 500 ms. Removing one command will allow
drive operation.
EF0 External fault GPD 503 is in Stop mode.
EF3 Ext. fault signal at term. 3 A fault condition has occurred in the external circuit(s)
EF5 Ext. fault signal at term. 5
monitored by the contact providing input to the indicated
EF6 Ext. fault signal at term. 6
terminal.
If display is steady, GPD 503 is in Stop mode; if display
EF7 Ext. fault signal at term. 7 is blinking, the terminal is programmed to allow continued
EF8 Ext. fault signal at term. 8
operation after receiving fault input.
E r r Constant write-in fault Temporary display, in Program mode, indicating that
constant setting was not written into EPROM memory.
FAn Cooling fan failure GPD 503 is in Stop mode.
FU Fuse blown DC Bus fuse has cleared. Check for short circuit
in output, and check main circuit transistors.
GF Ground fault protection Ground current > approx. 50% of the GPD 503 rated
current.
oC Overcurrent GPD 503 output current exceeds 200% of GPD 503
rated current, or ground fault has occurred, with ground
current exceeding 50% of GPD 503 rated current.
oH Heat sink overheated Fin temperature exceeds 90° C (194° F)
oH2 External overheat External temperature monitoring circuit(s) detected an
(blinking) overtemperature condition and produced an input signal.
oL1 Overload Thermal motor overload protection has tripped.
oL2 Overload GPD 503 overload protection has tripped.
oL3 Overload GPD 503 output torque exceeds the set Overtorque
(blinking) Detection level, but GPD 503 is programmed for
continued operation at overtorque detection.
oL3 Overload GPD 503 output torque exceeds the set Overtorque
Detection level, and GPD 503 is programmed for
coast to stop at overtorque detection.
oPE01 * kVA constant setting fault Sn-01 setting is incorrect.
oPE02 * Constant setting range fault An-XX, bn-XX, Cn-XX, or Sn-XX setting range fault.
oPE03 * Constant set value fault Sn-15 to -18 (multi-function input) set value fault.
oPE04 * Constant set value fault PG constant, number of poles, or PG division rate set
incorrectly.
oPE10 * Constant set value fault Cn-02 to -08 (V/f data) set incorrectly.
oPE11 * Constant set value fault One of the following conditions was detected:
• Cn-23 > 5 KHz and Cn-24
≤
5 KHz
• Cn-25 > 6 and Cn-24 > Cn-23
* These fault displays occur only when in the Program mode, when changing back to
Drive mode from Program mode, or when applying power to the GPD 503.
