GSK GS2000T Series Error Codes

33 codes from pages 119–123 of the manual

This is the list of alarm, fault codes the GSK manual gives for the GS2000T Series AC servo drive unit. Find your code below and open it for what the manual says about its causes and what to do.

Alarm codes from p. 119

CodeWhat it meansPage
Err-1 Motor speed exceeds the setting value of parameter PA54. p. 119
Err-2 Main circuit DC bus voltage is excessive. p. 119
Err-3 Main circuit DC bus voltage is too low p. 119
Err-4 The value in position deviation counter exceeds the setting value (refer to the range set by parameter PA32); (When PA137=0, detects the position deviation alarm, when PA137=1, does not detect the position deviation alarm) p. 119
Err-5 Alarm for the motor's excessive temperature (Err-5 alarms when the motor's overheating protection function is used) p. 119
Err-6 Speed amplifier saturation failure p. 119
Err-7 The drive prohibition is abnormal (occurs when PA138=1) p. 121
Err-8 Position deviation counter overflow (it occurs when Err-4 alarm is shielded) p. 121
Err-9 The motor encoder signal feedback is abnormal. p. 121
Err-11 Servo unit internal IPM module failure p. 121
Err-12 Alarm for overcurrent p. 121

Fault codes from p. 122

CodeWhat it meansPage
Err-16 Motor's heat is overload p. 122
Err-17 Braking time is too long p. 122
Err-18 No braking feedback corresponds to braking enable signal p. 122
Err-19 The DC bus voltage is excessive, but there is no braking. p. 122
Err-20 EEPROM alarm occurs in the servo unit after power-on. p. 122
Err-21 Open phase of power supply alarms p. 122
Err-23 The current sample is wrong p. 122
Err-28 Software upgrading parameter error p. 122
Err-29 Parameter error detected after power-on p. 122
Err-30 Excessive AC input voltage alarm p. 122
Err-32 Encoder UVW signals are illegal codes. p. 122
Err-33 The power supply charge is fault p. 122
Err-34 Excessive pulse electronic gear ratio p. 122
Err-35 The external brake pipe is fault p. 123
Err-36 Three-phase main power down p. 123
Err-37 Alarm occurs when the temperature of radiator is below -20°C. p. 123
Err-38 Alarm occurs when the temperature is higher than 75°C. p. 123
Err-39 For the absolute encoder, the read data is wrong in sensor mode. p. 123
Err-42 Reading EEPROM in the absolute encoder is wrong p. 123
Err-43 The check is wrong when EEPROM is read in the absolute encoder p. 123
Err-44 Allocation between single-circle and multi-circle of the encoder are wrong p. 123
Err-45 The encoder data's check is wrong p. 123
