Replacing an Older SD17063
The older SD17063 stepper drive has also been phased out and replaced by the SD17063 rev. B. The older
SD17036 is still supported by AMCI but it is no longer sold as a new unit. The SD17063 rev. B has several
additional features but the two drives are basically the same. The new Current Loop Gain feature, and
improvements to the Idle Current and Anti-Resonance features, are the primary enhancements to the
SD17063 rev. B drive.
DIP Switch Settings
The older SD17063’s have only three switch blocks, labeled SB1 through SB3 while the SD17063 rev. B has
four blocks. Settings from the older SD17063 can be directly transferred to the newer drive by using the table
below. (If the older drive has a switch is on, the SD17063 rev. B should also have it on.) The table contains
four columns. The first is the name of the feature, the second is the switch used by the older SD17063 and the
third is the switch used by the SD17063 rev. B. The fourth column is for comments.

Indexer Connector Wiring
The Indexer Connector can be plugged directly into the SD17063 rev. B without wiring changes.
Motor Connector Wiring
The Motor Connector can be plugged directly into the SD17063 rev. B without wiring changes.
Power Connector Wiring Changes
The grounding wire from the drives Grounding Lug must be installed on the SD17063 rev. B. The IEC con-
nector on the old SD17063 must be cut off, the wires stripped and installed in the supplied power connector.
See figure 5.10, Power and Grounding Connections on page 41 for more information.
Improving Upon an Older SD17063 Installation
Improvements in your system may result from setting the Current Loop Gain and Anti-Resonance Phase fea-
tures on the SD17063 rev. B, which is done during the systems initial test. If your system does not require
holding torque from the motor, consider changing the Idle Current Reduction setting to eliminate motor cur-
rent when the motor is idle. The To 0% setting is chosen when SB2-2 and SB2-3 both equal zero.
After your installation is complete, you should test the system using the procedures given in Step 6: Testing
the System, starting on page 42.

Comments
Anti-Resonance Enable SB1-1 SB1-2
Anti-Resonance Phase SB1-3 = 0 May change setting while testing the system.
Idle Current Reduction SB1-2
SB2-2 = SB1-2
SB2-3 = 1
SB2-2 on Rev. B drive is set the same as switch
SB1-2 on older drive. SB2-3 = 1. This sets Idle
Current Reduction to Not Reduced or To 50%.
Pulse Train Input SB1-3 SB1-1
Output Waveform SB1-4/5 SB2-4/5
Step Resolution SB2-1/2/3/4 SB3-1/2/3/4
Motor Current SB2-5 & SB3 SB3-5 & SB4
Current Loop Gain SB1-4/5 = 0 May change setting while testing the system.
Current Control SB2-1 = 0 Sets drive for RMS current control.
