PROGRAMMABLE PARAMETERS

The 1223/33, 1225/35, and 1227/37 controllers have a number of parameters

that can be programmed by means of a 1307 handheld programmer. These

programmable parameters allow the vehicle’s performance characteristics to be

customized to ﬁt the needs of individual vehicle operators.

Each controller is shipped with the parameter settings speciﬁed by the

OEM. For each programmable parameter, the speciﬁcation process includes

designating whether it is to have User or OEM-only access rights. In consultation

with Curtis PMC applications engineers, the OEM speciﬁes which—if any—

parameters the user (dealer, distributor, etc.) will be able to adjust. Accordingly,

Curtis PMC offers two versions of the 1307 programmer: the 1307-1101 is the

User programmer (which can adjust only those parameters with User access

rights) and the 1307-2101 is the OEM programmer (which can adjust all the

programmable parameters).

The MultiMode™ feature of these controllers allows operation in two

distinct modes: “Mode 1” and “Mode 2.” These modes can be programmed to

provide two different sets of operating characteristics, which can be useful for

operation in different conditions. For example, a mobility aid scooter might have

Mode 1 programmed such that the vehicle moves slowly for precise, indoor

maneuvering and Mode 2 programmed for higher speed, long distance travel

outdoors.

Seven parameters can be conﬁgured independently in the two modes:

— acceleration rate (M1, M2)

— forward deceleration rate (M1, M2)

— reverse deceleration rate (M1, M2)

— maximum speed (M1, M2)

— minimum speed (M1, M2)

— IR speed compensation (M1, M2)

— main current limit (M1, M2).

If a momentary switch is used to change modes, the controller defaults to

Mode 1 when power is ﬁrst applied. If an indicator LED is used with the

momentary switch, it will be lit when the controller is in Mode 1.

If an on/off switch is used to change modes, the switch position determines

the mode in which the controller powers up. The controller is in Mode 2 when

the mode input is connected to B+ with the on/off switch type conﬁgured.

Leaving the mode input floating or actively pulling it to B- puts the controller in

Mode 1.

Controllers can be factory-set to allow only one mode of operation if a

MultiMode™ system is not desirable for the application—see Section 4.
