Event "70:Parameter consistency"
1: no servoencoder; control mode B20 is set to "servo" but no appropriate encoder is selected
(B26, H.. parameter).
2: X120 direction; X120 is used as source in one parameter but is parameterized in H120 as drain
(or vice versa).
3: B12<->B20; Control mode B20 is not set to servo but the nominal motor current (B12) exceeds
the 4-kHz nominal current (R24) of the device by more than 1.5 times.
4: B10<->H31; Resolver/motorpoleno.; the set motor pole number (B10) and the resolver pole
number (H31) do not match.
5: Neg. slip. With use of control modes V/f, SLVE or Vector Control (B20): Control mode to "ASM":
A negative slip results from the values for nominal motor speed (B13), nominal motor frequency
(B15) and motor pole number (B10).
7: B26:SSI-Slave; SSI slave may not be used as motor encoder (synchronization problems)
8: C01>B83; C01 may not be greater than B83.

Device control state: State of the device state machine. The device state machine enables or
disables the drive function and the power module (application on the active axis).
0: Self-test; The inverter is executing a self test and calibration procedure and cannot be enabled
yet. The drive function is disabled. The device state automatically changes after a short time to
1:Switch on inhibit.
1: Switch-on disable; This device state prevents an automatic restart during device startup and with
the fault acknowledgment. The drive function is disabled.
The device state can change to 2:Ready for switch-on when
- The startup disable ASP5000 permits operation (E67Starting lockout = 0:inactive)
- The DC link is charged via the charging circuit
- The enable is inactive
- A possible axis switch is finished
NOTE
Remember that the change in device status from 1:Switch on inhibit to 2:Ready for switch-on
depends on parameter A34.
2: Ready for switch-on; The DC link is charged; E67Starting lockout is inactive; any possible axis
switch is finished. The drive function is disabled.
If the enable becomes active now, the device state changes to 3:Switched on.
3: Switched on; The DC link is charged; E67Starting lockout is inactive; the power module is being
prepared for operation. The drive function is disabled.
The device state changes to 4:Enabled after the longer of the two times 4 msec or A150 cycle
time.
4: Enabled; The drive function is enabled. Reference values are processed.
5: Fault; A fault has occurred. The fault memory was written. The drive function is disabled. The
device state can changed to 1:Switch on inhibit when the fault is acknowledged.
NOTE
Remember that the change in device state from 1:Switch on inhibit to 2: Ready for switch-on
depends on parameter A34.
6: Fault reaction; A fault has occurred. The fault memory is being written. When A29 fault-quick
stop occurs, the drive function remains enabled for the time of the quick stop. The device state
changes to 5:Fault when
- The fault memory is written AND either
- The power module must be switched off (e.g., for short circuit or ground fault)
- A67 Start up inhibit becomes = 1:active or
- A29 Fault quick stop is = 0:inactive or
- The quick stop ends (in standstill after maximum A39 t-max Q-Stop or with enable = inactive) or
- When E06 DC-link-voltage becomes less than 130 V.
7: Quick stop; A quick stop was triggered; the inverter moves with the quick stop ramp, speed-
controlled, to a standstill. The drive function remains enabled for the time of the quick stop. After
the quick stop is concluded, the device state changes (depending on the device control in the
global area, A39 t-max. Q-stop, A44 enablequick-stop, A45 quick stop end).
