Motor Position Sensor Inputs; Table 14 Can Ports Electrical Specifications - Kohler Curtis F Series Manual

Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022
The supported protocol is CANopen Physical layer ISO 11898, including the 11-bit and 29-bit
identifier protocols. For applications with multiple third party devices, refer to the CANopen Physical
Layer for the recommended bit timing settings and bus lengths based upon baud rate.
Use Port 1 (CAN1) for the communication channel with the Curtis Integrated Toolkit
and the 1313 HHP programmer. See Appendix D for the CAN port hardware configuration to utilize
these programming tools. This applies to both non-isolated and isolated CAN controller models.
There are 30 CAN receive mailboxes and 20 CAN transmit mailboxes. These are shared between
both CAN ports. Attempting to assign more than this using the Assign_CAN_Mailbox() function
will return an error. See the System Information file.
There are four TPDO and four RPDO mailboxes, each for CAN Port 1 and Port 2. See the CAN
Interface and CAN Interface 2 menus in Programmer.

Motor Position Sensor Inputs

The controllers running cdev 4.0.0.0 (FOS 4.0 or later) operate AC induction (ACIM) and AC
Permanent Magnet Motor (PMAC) motors. To accomplish this, the rotor position inputs accept
various types of sensors.
• 2-channel Quadrature encoders.
• Open Collector (OC) encoders.
• Sine/Cosine Position sensors (encoder).
• Hall switch devices.
When configured as a digital Quadrature Encoder, the input is a 2kΩ pull-up resistor to +5V.
When configured as a Sine/Cosine Analog Encoder, the inputs are setup as analog inputs. These
sinusoidal analog signals are mathematically converted to rotor position.

CAN Termination
Non-isolated 35 pin units:
Short pins 21 and 34 with external jumper
engage 120 Ohm termination.
Isolated and 23 pin units:
120 ohm termination is a hardware option.
Non-isolated & isolated CAN:
No internal termination.
