[Mtr Inertia]
Inertia of motor attached to drive. Automatically
changed when [Motor Type] is changed (to motor
is inertia + 20% for coupling) (Inertia is defined
as time in milliseconds required to reach 1000
rpm at rated motor current). It is used as input to
the auto tune procedure.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".

Default Value 100 msec
[Mtr Peak Cur]
Motor peak current.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".

Default Value Rated motor peak current
[Mtr Pole Cnt]
The number of electrical poles on the motor.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".
Parameter Numbers 396
Parameter Group Mtr Data
Display Units None
Parameter Type Read/Write
Change While Running No
Linkable No
Minimum Value 2
Maximum Value 8
Default Value This is determined by the motor catalog number.
[Mtr Rated Cur]
Motor nameplate rated current. Automatically
changed when [Motor Type] is changed. This
value will be clamped to the current rating of the
axis module if the motor rating is larger than the
module.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".

Linkable No
Minimum Value 0%
Maximum Value 100%
Default Value 0%
[Neg Cur Lim]
The maximum allowable negative motor current
that can be commanded is specified through this
parameter. If greater than [Bridge Lim], then
[Bridge Lim] will set the limits.
Important: Setting this parameter to a value other
than default will limit motor output torque in CCW
direction.
For Example: If the value equals 100%, the axis
module will not deliver more than 100% to motor,
thus peak torque is limited to 100%.
