Parameter mm.000
Parametermm.000 (mm.000) is one parameter that can be accessed from every drive menu so that the user can initiate various actions by setting a
value in this parameter and then performing a drive reset. If the action is completed successfully parameter mm.000 is cleared when the action is
complete. If the action is not started because the value does not correspond to an action, or because the action is not allowed (i.e. an attempt is made
to load defaults and the drive is enabled), parameter mm.000 is not cleared. If the action is started and then fails a trip is produced and parameter
mm.000 is not cleared.
There could be some conflict between the actions of Parametermm.000 (mm.000) and ParameterCloning (11.042) when the drive is reset. If
ParameterCloning (11.042) has a value of 1 or 2 and a valid action is required from the value of parameter mm.000 then only the action required by
parameter mm.000 is performed, but on successful completion of the action both parameters are cleared. If ParameterCloning (11.042) has any other
value it is not affected.
The table below shows the possible actions that can be initiated with Parametermm.000 (mm.000).

Saving drive parameters
User-save and power-down save drive parameters are stored in non-volatile memory within the drive. Any values that have changed are copied to this
memory under the following conditions.
Unidrive M700 Parameter Reference Guide
Issue: 01.16.01 (Eth 01.07.00) 5

Parameter type Conditions for copy to non-volatile memory
User-save parameter
not visible in menu 0
Drive reset with 1000 in Parametermm.000 (mm.000) if the drive is not in the under voltage state and the standard under
voltage threshold is being used (i.e. LowUnderVoltageThresholdSelect (06.067) = 0).
OR
A drive reset with 1001 in Parametermm.000 (mm.000).
OR
After parameters are transferred from a non-volatile media card.
OR
After the drive mode is changed.
OR
After default parameters are loaded.
OR
After parameters are transferred from an electronic nameplate.
User save parameter
visible in menu 0
Under the conditions given above for user save parameters not visible in Menu 0.
OR
If the keypad is in edit mode for a user-save parameter in Menu 0, the parameter is saved when the keypad mode is
changed from edit mode.
Power-down save
parameter
A drive reset with 1000 in Parametermm.000 (mm.000) if the drive is not in the under voltage state and the standard under
voltage threshold is being used (i.e. LowUnderVoltageThresholdSelect (06.067) = 0).
OR
A drive reset with 1001 in Parametermm.000 (mm.000).
OR
On the transition into the under voltage state when the standard under voltage threshold is being used (i.e.
LowUnderVoltageThresholdSelect (06.067) is zero).
OR
After the drive mode is changed.
OR
After parameters are transferred from a non-volatile media card which results in the drive mode changing.
It can take some time for parameter data to be copied to non-volatile memory, especially if there are a large number of differences between the
parameter values in the drive and the values stored in the memory. Saving Power-down save parameters takes a maximum of 300ms, but saving user-
save parameters can take several seconds. If the drive is powered from a 24V control supply, or from a low voltage supply, the power down time of the
control system can be very short and there is a risk that either the stored values of the power-down save or user-save parameters could be corrupted.
This would result in an EEPROMFail trip at the next power-up. To reduce this risk, the power-down save and user-save parameters are each stored in
two banks. The banks are alternated each time a save is performed and the bank pointer is only updated once the save is complete. If the new bank is
corrupted a UserSave or PowerDownSave is initiated at the next power-up indicating an error in the user-save or power-down save data respectively,
and the data from the old bank is used. The following points should be noted:
1. If a UserSave or PowerDownSave trip occur at power-up then parameter changes made before power down will be lost. To clear these trips a
parameter save must be performed. If both the user-save and power-down save data is corrupted then a PowerDownSave trip is produced.
2. When a Menu 0 parameter is changed its value is saved immediately to the active bank and the bank pointer is not changed. Therefore
changes made via Menu 0 are not lost if a UserSave trip occurs at power-up.
3. When the drive mode changes all the data in both banks in the non-volatile memory is cleared and the default parameters are saved in both
banks. Therefore there is an extended parameter saving period immediately after a drive mode change.
4. Two banks are not provided in non-volatile media cards therefore the card could be corrupted if the power is removed when the drive is writing
data to the card.
Loading defaults
A drive reset with 1233 in Parametermm.000 (mm.000) loads the defaults defined for each parameter. If defaults are loaded with 1244 in Parameter
mm.000 (mm.000) then the parameters in the table below have different defaults that are intended for the 60Hz regions.

Non-volatile media card data transfer
Details of the data that can be stored on a non-volatile media card and the methods to transfer/access this data are given in Menu 11.
Stored HF trips
When the drive is subsequently powered up a StoredHF trip is initiated where the sub-trip number is the number of the HF trip that last occurred. This
trip will occur at every power-up until it is reset. The trip can only be reset by first entering 1299 into Parametermm.000 (mm.000). If the drive is
powered up and a StoredHF trip occurs, OnboardUserProgram:Enable (Pr 11.047) is reset to zero to prevent the on-board user program from
running. This ensures that the user program can be changed or erased in case it causes an HF trip at every power-up. Once the StoredHF is cleared, it
is necessary to power cycle the drive or to re-download the user program to allow the program to restart.

Variable Minimum / Maximum Pairs
The descriptions below define the variable minimum/maximum pairs that can be used with parameters when the VM format bit is set. The variable
minimum and maximum themselves can be dependent on other parameters, or the drive rating or other conditions as defined. The variable minimum
and the variable maximum have a limited range and this is defined for each minimum/maximum pair.

RFC-A, RFC-S: 0.000
Range of [MAX] Open-loop: 0.0 to 3200.0
RFC-A, RFC-S: 0.000 to 3200.000
A maximum needs to be applied to the ramp rate parameters because the units are a time for a change of speed from zero to a defined level or to
maximum speed. The defined level is 100Hz for Open-loop mode and 1000rpm or 1000mm/s for RFC-A and RFC-S modes. If the change of speed is to
the maximum speed then changing the maximum speed changes the actual ramp rate for a given ramp rate parameter value. The variable maximum
calculation ensures that longest ramp rate (parameter at its maximum value) is not slower than the rate with the defined level, i.e. 3200.00 s / Hz for
Open-loop mode, and 3200.000 s / 1000rpm or 3200.000 s / 1000mm/s for RFC-A and RFC-S modes.
The maximum frequency/speed is taken from MaximumReferenceClamp (01.006) if SelectMotor2Parameters (11.045) = 0, or M2Maximum

VM_POSITIVE_REF_CLAMP1[MAX] defines the range of the positive reference clamp, MaximumReferenceClamp (01.006), which in turn limit the
references. In RFC-A and RFC-S modes a limit is applied so that the position feedback does not exceed the speed where the drive can no longer
interpret the feedback signal correctly as given in the table below. The limit is based on the position feedback device selected with MotorControl
FeedbackSelect (03.026). It is possible to disable this limit if the RFCFeedbackMode (03.024) ≥ 1 (i.e. VM_POSITIVE_REF_CLAMP = 50000.0), so
that the motor can be operated at a speed above the level where the drive can interpret the feedback in sensorless mode. It should be noted that the
position feedback device itself may have a maximum speed limit that is lower than those given in the table. Care should be taken not to exceed a speed
that would cause damage to the position feedback device.

Any other device 50000.0 rpm or mm/s
The limit ensures that the frequency of incremental digital or sine wave signals from the encoder do not exceed 500kHz and the modulation frequency
for a resolver does not exceed 1kHz, neglecting any speed controller overshoot. The position feedback resolution remains fixed over the whole
frequency for digital signals, but reduces with increased frequency or reduced voltage with sine wave signals. The position resolution with sine wave
signals is given by the equations below.
Position resolution for a rotary device = K x sine waves per revolution
Position resolution for a linear device = K x sine waves per pole pitch
The value of K varies with the frequency and magnitude of the sine wave signals. The nominal value of K is 1024, and the drive interface provides at
least this resolution with 1.0Vp-p sine waves up to a frequency of 50kHz. The table below shows the variation of K with sine wave peak to peak voltage
and frequency.

VM_POSITIVE_REF_CLAMP[MAX] in Open-loop mode is fixed at 3000.0 as position feedback cannot be used for motor control.
VM_POSITIVE_REF_CLAMP[MIN] = 0.0
(Note: An additional limit is applied to ensure that the drive output frequency cannot exceed 550Hz. For Open-loop mode an additional limit of 550Hz is
applied directly. For RFC modes the variable maximum is applied to the speed reference, and an additional limit of 550 x 60 / Motor pole pairs is
applied.)

FireModeActivate (01.054) cannot be written directly, but it can be controlled from a digital input. This prevents fire mode from being enabled from the
keypad, comms or an option module.
Fire mode is intended for purging air from a ventilation system in the event of a fire. All trips are either disabled or are automatically reset after 1s. The
use of fire mode can result in damage to the drive, and so if fire mode is enabled and any trip is initiated an indication that cannot be reset by the user is
stored in PotentialDriveDamageConditions (10.106). For Open-loop, RFC-A or RFC-S modes fire mode is activated and if FireModeReference
(01.053) has a non-zero value and FireModeActivate (01.054) = 1. When fire mode is activated normal drive operation is overridden as follows.
1. Pre-rampReference (01.003) is forced to the value in FireModeReference (01.053).
2. The Final drive enable is forced to be active provided the safe torque off hardware input will allow the drive to be enabled. The Final drive run is
forced to be active.
3. ForwardLimitSwitch (06.035) and ReverseLimitSwitch (06.036) are disabled.
4. HardSpeedReference (03.022) is forced to 0 (RFC-A and RFC-S modes). The hard speed reference should not be used when fire mode can
be activated as this could cause an abrupt change in speed.
5. The hand/off/auto system is disabled. If this system is in the hand state when fire mode is activated it will be forced to the off state, so that hand
state is not active when fire mode is de-activated.
6. Keypad control mode is disabled.
7. All latched states in the sequencer (Menu 6) are reset.
For Regen mode fire mode is activated if FireModeActivate (01.054) = 1. When fire mode is activated the Final drive enable is forced to be active
provided the safe torque off hardware input will allow the drive to be enabled.
If the drive is in the tripped state when fire mode is activated the trip is reset and then only the trips listed in the table below can be initiated whilst fire
mode is active. If any of the trips shown as resettable occur, the drive will attempt to automatically reset the trip after 1s.
