6.22.12 Frequent causes of error
Servo drive cannot
be switched on
The servo drive cannot be switched on or does not move:
1 Check whether the drive was enabled by the CC.
Selection: Login Ipo/Axes/Ipo Act State 1: ANTRIEB_FREI ()
ANTRIEB_FREI=false: Presumably an error on the CC or a hardware
problem
2 Check whether "Drive on" was requested by the PLC.
Selection: Login Ipo/Axes/Plc Nom State: DriveOnReq ()
AntriebEin=false: probably error in the PLC program
3 Check whether the drive was switched on.
Selection: Login Ipo/Axes/Ipo Act State 1: ANTRIEB_EIN ()
ANTRIEB_EIN=false: probably IPO internal error
4 Check whether position feedback control was requested by the PLC.
Selection: Login Ipo/Axes/Plc Nom State: PosCtrlRequest (does not apply
to spindles)
PosCtrlRequest=false: probably error in the PLC program
5 Check whether position feedback control is active.
Selection: Login Ipo/Axes/Ipo Act State 1: LGR_AKTIV
6 Check whether "feed rate enable" was set by the PLC.
Selection: Login Ipo/Axes/Plc Nom State: VorschubFreigabe
Servo drive does
not move
The servo drive cannot be switched on or does not move although all enabling
commands are available—check the following variables:
1 The maximum permissible axis feed rate must be > 0.
Selection: Login Ipo/Axes/Plc Nom Data: MaxAchsVorschub
MaxAchsVorschub = 0: probably an error in the PLC program
2 The axis override must be > 0.
Selection: Login Ipo/Axes/Plc Nom State: AchsOverride
AchsOverride = 0: probably error in the PLC program
3 The IPO nominal speed must not be equal to 0.
Selection: Login Ipo/Axes/Ipo Act Data: absSollV
absSollV = 0: probably IPO internal error
4 The IPO actual speed must not be equal to 0.
Selection: Login Ipo/Axes/Ipo Act Data: absIstV
absIstV = 0: probably IPO internal error
