1821 Reference counter size for each axis
NOTE When this parameter has been set, the power must
be turned off before operation is continued.
[Data type] 2-word axis [Valid data range] 0 to 99999999
Set the size of the reference counter. When an encoder with absolute address reference marks (linear scale or rotary encoder) is to be used, set the interval of mark 1 on the encoder with absolute address reference marks (linear scale or rotary encoder).
NOTE With a scale with the absolute address zero point

1825 Servo loop gain for each axis

Set the loop gain for position control for each axis. When the machine performs linear and circular interpolation (cutting), the same value must be set for all axes. When the machine requires positioning only, the values set for the axes may differ from one another. As the loop gain increases, the response by position control is improved. A too large loop gain, however, makes the servo system unstable. The relationship between the positioning deviation (the number of pulses counted by the error counter) and the feedrate is expressed as follows:
Feedrate Positioning deviation =

If the value specified with this parameter is exceeded at servo-off time, a servo alarm (No.410) is issued to cause an immediate stop (same as an emergency stop). Usually, set the same value as a positional deviation at stop time (parameter No.1829).

NOTE When bit 0 (PLC01) of parameter No.2000 is set to
1, a value ten times greater than the value set in this parameter is used to make the check.

zero point of the encoder to the reference position exceeds 99,999,999.
1885 Maximum allowable value for total travel during torque control
[Data type] Word axis [Unit of data] Detection unit [Valid data range] 0 to 32767
This parameter sets the maximum allowable value for the total travel (error counter value) for an axis placed under torque control, as specified by the axis control command of the PMC axis control function. If the total travel exceeds the parameter-set value while torque control is applied, a servo alarm (No.423) is generated.
NOTE This parameter is enabled when the TQF
parameter (bit 4 of parameter No.1803) is 0 (follow-up is not performed during torque control).
1886 Positional deviation when torque control is canceled
[Data type] Word axis [Unit of data] Detection unit [Valid data range] 0 to 32767
This parameter sets the positional deviation used when torque control, performed for an axis according to the axis control command of the PMC axis control function, is canceled and position control is resumed. After the positional deviation has fallen to the parameter-set value, switching to position control is performed.
NOTE This parameter is enabled when the TQF
parameter (bit 4 of parameter No.1803) is 0 (follow-up is not performed during torque control).

[Data type] Bit axis FSLx The type of interface used between the servo amplifier and servo
software is: 0 : Fast type. 1 : Slow type. The user can choose between two interface types for servo data transfer: fast type or slow type. Set this parameter so that the following conditions are satisfied: • When a one-axis amplifier is used, either the fast type or slow
type interface can be used. • When a two-axis amplifier is used, the use of the fast type for
both axes is not allowed. The slow type can be used for both axes.
• When a three-axis amplifier is used, the requirement for a two-axes amplifier described above applies to the first and second axes, and the requirement for a one-axis amplifier, again described above, applies to the third axis.
• When an odd number is specified for parameter No.1023, the fast type interface must be used. However, the slow type may be used for high-speed current loop axis and high-speed interface axis.
• When an even number is specified for parameter No.1023, only the slow type interface can be used. (The FSL bit must always be set to 1.)

[Data type] Byte axis [Valid data range] 0 to 7
When a separate detector interface unit is used, each of these parameters sets the value obtained by subtracting 1 from a separate detector interface unit connector number for each axis. That is, values of 0 through 7 are set for connector numbers 1 through 8. In addition, bits 6 and 7 of parameter No.1905 must be set. For an axis that does not use a separate detector interface unit, 0 must be set. Any connector can be used for any axis, however the connectors in a single separate detector interface unit should be used in ascending order of connector number. For instance, connector 4 of a separate detector interface unit cannot be used without using connector 3 of the same separate detector interface unit. Example

- 164 -
This parameter sets a password for protecting program Nos. 9000 to 9999. When a value other than zero is set in this parameter and this value differs from the keyword set in parameter No.3211, bit 4 (NE9) of parameter No.3202 for protecting program Nos. 9000 to 9999 is automatically set to 1. This disables the editing of program Nos. 9000 to 9999. Until the value set as the password is set as a keyword, NE9 cannot be set to 0 and the password cannot be modified.
NOTE 1 The state where password ≠ 0 and password ≠
keyword is referred to as the locked state. When an attempt is made to modify the password by MDI input operation in this state, the warning message "WRITE PROTECTED" is displayed to indicate that the password cannot be modified. When an attempt is made to modify the password with G10 (programmable parameter input), P/S alarm No.231 is issued.
