Product Description:
The SS2000MD7-RC-100 is a stepper motor drive produced by Kollmorgen that is intended to operate bipolar stepper motors by utilizing digital step and direction signals. The unit is panel-mounted and features integrated flange ears, as well as a ribbed passive radiator for thermal management.
The DC input voltage range of the SS2000MD7-RC-100 stepper motor drive is 24 to 75 volts, and it can draw up to 4 amps of current. The drive is compatible with bipolar stepper motors and enables the selection of phase currents between 1 amp and 5 amps via DIP switches 1 to 6. The current levels are configured as follows: 1A (000001), 2A (000010), 3A (000100), 4A (001000), and 5A (010000) using binary DIP settings, where "0" indicates OFF and "1" indicates ON. A full step (00), 2 microsteps (10), 10 microsteps (01), and 20 microsteps (11) are the options for microstepping resolution, which is configured through DIP switches 7 and 8. Although it is undocumented and presumably employs an override condition, an additional inferred setting offers 50 microsteps. The motor drive is equipped with an enable/disable input pin and accepts TTL-compatible step and direction inputs. The motor phase connections are easily identifiable and can be wired using either Molex connectors or screw terminals. They are labeled A+, A−, B+, and B−.
The SS2000MD7-RC-100 stepper motor drive has a passive heat radiator that keeps the performance stable and keeps the temperature from building up during long periods of use. The flanged ears on the mounting format allow direct placement in panel-based enclosures without the need for extra attachments. The TTL-level inputs on the drive make it work with most common motion devices. It is possible to change the current and step resolution settings on the motor drive to get different power and smoothness levels.
Frequently Asked Questions about SS2000MD7-RC-100:
Q: Why does SS2000MD7-RC-100 have TTL-compatible control inputs?
A: TTL compatibility allows seamless integration with standard motion controllers that output 5V logic. It ensures signal accuracy and minimizes interface conversion requirements.
Q: Why does SS2000MD7-RC-100 offer a 24–75 VDC input range?
A: This wide voltage range ensures operational flexibility with various power supplies. It supports consistent drive performance across different machine configurations.
Q: Does SS2000MD7-RC-100 support microstepping configurations?
A: Yes, it supports full steps to 20 microsteps through DIP settings. An undocumented mode likely offers 50 microsteps for smoother motor movement.
Q: How do DIP switches control SS2000MD7-RC-100 phase current?
A: Six DIP switches allow selection from 1A to 5A output. This helps match motor torque requirements without external programming.
Q: Why does SS2000MD7-RC-100 use passive heatsink cooling?
A: The ribbed housing dissipates heat without active components. This simplifies maintenance and ensures temperature stability during prolonged use.
