Page 4: Product Overview
Configuration The ACR7000 requires a short set up process before motion or programming is possible. PMM assists the user with these settings in a step-by-step configuration wizard. The user is prompted to input key application information such as motor model number, mechanical scaling, limits conditions, etc. The configuration process is completed with the download of the System Code. - Page 5 PC applications and constructing drivers. HMI Based Applications Parker Xpress and InteractX HMI families include a built-in driver for communications with the ACR7000. The Acroloop CIP Ethernet driver supports exchange of flag/bit data, 32-bit integers and floating parameters and ASCII strings.

Page 8: Mechanical Installation
Mechanical Installation Environment & Cooling The ACR7000 operates in an ambient temperature range of 0°C (32°F) to 50°C (120°F) ambient air temperature. The drive can tolerate atmospheric pollution degree 2. Only dry, non-conductive pollution is acceptable. Therefore, it is recommended that the drive be mounted in a suitable enclosure. - Page 9 Mounting Guidelines The ACR7000 drive/controllers are vented products. To prevent material spilling into the drive, mount it under an overhang or in a suitable enclosure. ACR7000 products are made available under “Restricted Distribution” for use in the “Second Environment” as described in the publication EN 61800-3 ed2.0.

Page 19: Motion Enable Input
The Motion Enable Input MUST be connected to 24VDC in order to enable/power the motors. The input is considered active when 24 VDC is applied to PIN 17 of I/O connector 0. If the input goes inactive, that inactive state is latched and the ACR7000 reacts by doing the following: Disabling the drives •... -
Page 20: Stepper Drive Operation
ACR7000 Stepper User Guide Stepper Drive Operation The integrated stepper drives in the ACR7000 are configured using the Configuration Wizard in Parker Motion Manager Software. The necessary flags and parameters are included in the controller configuration and downloaded as part of the user project along with scaling, limits, program memory settings, etc. The following provides detail about these drive settings how the drives operate. - Page 21 P7938= 1.5 : REM User Maximum motor current (Amps) Standby Current In order to reduce the overall temperature of the motor, the user can specify a reduced motor current to be applied while the motor is idle. Standby Current Percentage parameter is the percent of the user selected maximum motor current that current should drop to after the standby period has elapsed.
