Frequently Asked Questions
How should I size the vertical-axis holding brake relative to load and gearbox?
Ensure reflected static torque at the motor shaft (load×gear ratio÷efficiency×radius) is below the 70 Nm brake torque and include a safety factor for back-driving. For long dwells, verify brake thermal limits and use mechanical countermeasures (e.g., counterbalance).
Does the A-side power connector affect cabinet and cable routing?
Yes, A-side means the power/flange socket exits on the A-flange, so plan motor orientation and bend radii to keep EMC-compliant cable lengths short. The code sheet defines “A” as the A-side socket option for MSK motors.
How do I pick an IndraDrive for this axis given the current and torque figures?
Match continuous and peak current to the motor’s ~35 A continuous and ~138 A peak and ensure the drive’s overload profile meets the duty cycle. Also verify regen energy handling for decel/braking events.
What integration notes apply when pairing the Hiperface encoder with third-party controllers?
Confirm the controller’s Hiperface master supports sine/cosine acquisition and absolute data framing per the protocol timing. Resolution per period is fixed (5 bits/period), so set scaling to 4,096 counts/turn for 128-period encoders.
Are MSK motors suitable for washdown or dusty environments?
The MSK platform is available with IP65 protection; choose matching sealed connectors and observe correct grounding to maintain rating. Avoid open cooling circuits which can introduce contaminants into the jacket.
