Version 365.000 & Up
NOTES:
(*1) Use supplied Contactor (GIGAVAC Part # GV200PA-1).
Use only a contactor WITHOUT A PWM AND COIL
SUPPRESSOIN. FAILURE TO DO SO CAN CAUSE
CONTROLLER FAILURE AND WILL VOID THE
WARRANTY.
(*2) Use supplied Pre-Charge Resistor and Relay (Tyco
Electronics Part # T9AP1D52-12).
For Coil connection, connect to small terminals.
(*3) Tachometers that are designed to work off of an ignition
coil may not function in this application. Some Tachometers
may need a pull up resistor of 4.7K Ω to function
(*4) A Battery Management System (BMS) is strongly
recommended if Lithium Ion batteries are used. Possible
source of BMS is Ewert Energy System’s ORION BMS
(www.orionbms.com)
(*5) Start switch is required if Idle or Creep Torque
parameters are ENABLED. See Programming Instructions.
A start switch CAN be used without IDLE.
See programming instructions for information
(*6) Install the Optional Clutch/Shift Switch so that is ON
when the clutch pedals is pressed. When clutch pedal is
pressed the regen setting is changed to Shift Neutral
Braking Parameter to prevent the motor from stalling during
gear shifting. In a clutch less system, this allows you to set
the coast down rate of the motor so that the gears align
properly.
See Instructions on SHIFT-NEUTRAL BRAKING
PARAMETERS.
(*7) Allows the use of ECONO Mode Parameters.
See Programming Instructions.
(*8) Forward is CLOCKWISE motor rotation from Encoder
end view. Depending on Transmission configuration, use
either wire to obtain desired rotation. Use FWD & REV
Switch in direct drive applications.
(*9) See Brake Schematics
(*10) Use Pack Fuse rated at 400A for Single controller
applications. For Dual controller use 800A Pack Fuse.
(*11) Only for Dual motor application. Use Controller Fuse
rated at 400A for each controller.
(*12) Gives access to Drive System information. Required to
access Programming and Diagnostic modes.
See Programming Instructions.
