Speed and Torque Control Mode
The following tables list and explain the meanings of bit data and code displays in
Speed, and Torque Control Modes.
Bit Data and Meanings in Speed and Torque Control Mode
Bit Datum Meaning
Control Power ON Lit when servo amplifier control power is ON.
Baseblock
Lit for baseblock.
Not lit when servo is ON.
Speed Coincidence
Lit when the difference between the motor speed and reference
speed is the same as or less than the value set in Pn503.
(The default value set in Pn503 is 10rpm).
/TGON
Lit if motor speed exceeds preset value
Preset value: Set in Pn502. (Default setting is 20rpm).
Speed Reference Input
Lit if input speed reference exceeds preset value.
Specified value: Set in Pn502. (Default setting is 20rpm)
Torque Reference Input
Lit if input torque reference exceeds preset value.
Preset value: 10% rated torque is default setting
Power Ready
Lit when main power supply circuit is operating at normal level.
Not lit when power is OFF.
