Line reactors

The Mentor MP, in common with all naturally commutated thyristor
drives, causes voltage notches at the input supply terminals. In order to
avoid disturbance to other equipment using the same supply, the
addition of external line inductance is strongly recommended in order to
restrict the depth of the notches imposed on the shared supply. This is
generally not necessary where a dedicated transformer is used to supply
the drive.
The following recommendations for added line inductance, have been
calculated based on the power drive systems standard: EN 61800-
3:2004 "Adjustable speed electrical power drive systems – Part 3: EMC
requirements and specific test methods".
NOTE
The current ratings specified in Table 4-2 are for typical motor currents
where the motor current ripple is no more than 50% of drive rating.

Field on / off. When L11 and L12 are open the supply is
L11, L12 disconnected to the field regulator so there will be no field
current.
F+, F- Field supply to the motor.
These terminals are used to provide feedback from the
motor armature terminals. This is required when the user
has a contactor in the main DC armature connection.
MA1, MA2
When the contactor is opened the drive will still be
receiving armature feedback. This allows the field
regulator to function correctly when the contactor is open.

Control 24Vdc supply

The 24Vdc input has three main functions.
• It can be used to supplement the drive's own internal 24V when
multiple SM-Universal Encoder Plus, SM-Encoder Output Plus, SM-
I/O Plus, or SM-I/O 32 modules are being used and the current
drawn by these modules is greater than the drive can supply. (If too
much current is drawn from the drive, the drive will initiate a 'PS.24V'
trip)
