6.3.1 Summarize
INMOTION company procreates controller ，adopt international advanced closed loop system and
advanced control technique。Designing large screen instrument，can clear display ―electric quantity‖、
―speed‖、―total time of run ‖，―work time of drive ‖，―work time of lift ‖and so on information。
Designation adopt code plus character manner，increase maintain efficiency。It also through meter
check periphery component to come true function of handset
(1) Actuating motor
Actuating motor adopt three-phase alternating current frequency conversion electromotor，increase
conversion efficiency，not have commentator brush in order not to maintenance 。
(2) Lift motor
Lift motor adopt three-phase alternating electromotor ，increase conversion efficiency，not have
commentator brush in order not to maintenance.
(3) Safety & protection features
① Reverse Polarity of the battery
② Connection errors
③ All inputs are protected against connections errors.
④ Current overload protection
⑤ It have detecting element，control peak current.
⑥ Thermal protection
If the controller temperature exceeds 85°C, the maximum current reduces in proportion to the thermal
increase. The temperature can never exceed 115°C.
If the electric machinery temperature exceeds 145°C, the maximum current reduces in proportion to the
thermal increase. The temperature can never exceed 165°C.
⑦ Low Battery charge
When the battery charge is low, the maximum current is reduced proportionally to the battery
discharge.
⑧ External Agents
Electric control is hermetical .The chopper is protected against dust and spray of liquid to economy.
⑨ Protection against accidental Start Up
A precise sequence of operations is necessary before the machine will start. Operation cannot
commence if these operations are not carried out correctly. Requests for drive must be made after
closing the Key Switch.
(4) Operational features
① Feedback control system make the vehicle speed follow accelerator ，whether low speed or not
high speed easy control .
② Two archives speed and acceleration design ，can apply to most situation.
③ Regeneration technology make change direction of fork even smooth。
