Resolver Wiring

Note: When positive voltage is sent to an axis’s drive, the axis must extend. The extend direction is defined as the direction that causes the transducer to return increasing counts.

Use shielded twisted pairs for all connections to inputs and outputs. Route the resolver wiring separate from other wiring.

RMC Resolver Input

Eight-Pin Plug-in Terminal Block

Pin	Function
R1	Reference Output +
Ref In	Reference In (normally not used)
R3	Reference Ouput -
S1	Sine Input +
S3	Sine Input -
S2	Cosine Input +
S4	Cosine Input -
Case	Controller chassis ground (shield)

Note: The RMC case must be mounted to a grounded panel or otherwise grounded to avoid Transducer Faults when operating at the 16-bit resolution setting.

RMC Drive Outputs

Four-Pin Plug-in Terminal Block

Pin	Function
1	Axis 0 Drive
2	Drive Common
3	Axis 1 Drive
4	Case

When positive voltage is sent to an axis’s drive, the axis must extend. The extend direction is defined as the direction that causes the transducer to return increasing counts.

CAUTION: If the outputs from the RMC are reversed, the axis will be uncontrollable when power is connected. Confirm that your wiring is correct!
