Control variables
(1) The following configuration and adjustment parameters do not revert to their factory settings; they retain their current configuration:
- bFr (Standard motor frequency) page
- LCC (Control via remote display terminal) page
- COd (Terminal locking code) page
- Communication parameters, page
(2) Note: the EEPROM life limit is 1,000,000 write operations.

Extended control word
bit 0 = 0: No action
bit 0 = 1: Recall factory settings command (1). This bit automatically resets to 0 when the request
is taken into account. It is only active when the drive has come to a complete stop:
ETI.4 = ETI.5 = 0.
bit 1 = 0: No action
bit 1 = 1: Save configuration/adjustments in EEPROM (2) if voltage is sufficient (no USF detected
fault). This bit automatically resets to 0 when the request is taken into account.
During saving (ETI.0 = 1), parameters cannot be written.
bit 2: Reserved
bit 3 = 0: No action
bit 3 = 1: External fault. The drive's behaviour during an external fault is defined by parameter
EPL (see page
).
bit 4 = 0: No action
bit 4 = 1: Ramp switching command
bits 4 to 8: Reserved
bit 9 = 0: Normal resolution (references, output speed and ouput frequency in physical units: rpm
and Hz)
bit 9 = 1: High resolution (references, output speed and ouput frequency in 32767 points for
600 Hz)
bits 10 to 12: Reserved
bit 13 = 0: Drive not locked on standstill
bit 13 = 1: Drive locked on standstill
bit 14 = 0: Control with Modbus communication monitoring
bit 14 = 1: Control with no Modbus communication monitoring (NTO)
bit 15 = 0: Parameter consistency check
bit 15 = 1: No parameter consistency check + drive locked on standstill (switching this bit to 0
will revalidate all parameters)
WARNING
LOSS OF CONTROL
If the CMI bit 14 (NTO) is set to 1,
communication monitoring will be inhibited. For safety
reasons, inhibition of communication interuption should only be used for adjustment or
special applications purpose.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.

IOLR R/W
Value of logic I/O
(0 = inactive, 1 = active)
bits 0 to 7: Not accessible in write mode
bit 8: Value of "R1" relay output, accessible in write mode if R1 is not assigned
bit 9: Value of "R2" relay output, accessible in write mode if R2 is not assigned
bit 10: Value of "LO" logic output, accessible in write mode if LO is not assigned
bits 11 to 13: Reserved
bit 14: Not accessible in write mode
bit 15: Reserved

AO1R R/W
Value of the analog output
AO1R is accessible in write mode if dO (page
) is not assigned
Variation range: 0 to 10000
The value 10000 corresponds to 10V if AO1t = 10U, or to 20 mA if AO1t = OA or 4A (page
